A voice conference is a call session made among three or more users. Depending on theconference convening mode, voice conferences can be classified into scheduledconferences and instant conferences.

Scheduled conference : A convener schedules a conference beforehand using a web-basedself-service system. If the web-based self-service system is unavailable, the convener asksthe enterprise administrator to schedule a conference. When the conference time arrives,participants can join the conference in any of the following three ways:

Individual dial-in Participants dial the conference access code and enter theconference ID and password as prompted to join the conference.

Moderator convening The moderator joins a conference and performs operations onthe phone to invite participants to join.

System convening The system automatically invites participants to the conference.

Instance conference : The moderator does not schedule a conference beforehand. Instead,he or she directly dials the conference access code on a terminal and then invitesparticipants to join when prompted.


10



The automatic switchboard service is also known as the interactive voice response (IVR)service. After a number is set as the automatic switchboard number and the automaticswitchboard service is enabled in an enterprise, all incoming calls are automaticallyforwarded to the automatic switchboard. The switchboard then plays announcements,prompting the calling party to perform operations accordingly. By default, the automaticswitchboard prompts the calling party to dial an extension number.

Enterprise administrators can customize switchboard announcements and multi-level IVRannouncements and configure the system to play varied announcements at different timeperiods of a day. The time periods can be configured by year, month, date, week, starttime, end time, and holiday.

The system supports a maximum of 256 automatic switchboards and a maximum of threelevels of IVR.


11



In an enterprise, employees in the same field can be added to a hunt group, with thegroup access code configured. When a user dials the group access code, the phones ofthe sign-in group members ring simultaneously, cyclically, or sequentially according to theconfigured routing policy. The hunt group service enables employees in the same field towork together for more efficient request processing.

A user can be added to multiple hunt groups to handle different service requirements.

When a call is connected to a hunt group through the hunt group access code, personalservices (such as call forwarding and DND) for the hunt group members, if enabled, will beunavailable.


12



Application Scenario

In an enterprise, employees in a department (for example, IT support department)have been added to a hunt group with a unified access code, and simultaneousringing has been configured for the hunt group. During the office hours, all groupmembers sign in to the hunt group. When a user dials the access code of this huntgroup, the phones of all employees in this hunt group ring at the same time. Afteran employee answers the call, the phones of the other employees stop ringing.

If sequential ringing is configured, the phone of the desired employee (whose phoneis expected to ring first according to the configured routing policy) rings first. If thedesired employee cannot answer the call, the call is diverted to the next expectednumber.

When no employee in the hunt group answers the call, the call is forwarded to theforward-to number configured for the hunt group access code. For example, thehunt group has configured call transfer to the voice mailbox upon ringing timeout.During the break, if a user dials the hunt group access code, no one answers thecall. When ringing times out, the system asks the user to leave a message. After theuser leaves a message, the MWIs on the phones of all members in the hunt groupare lit up. When the group members go back to work and find that the MWI is on, amember presses the corresponding button on the phone, enters the password, andlistens to the message. Then, the MWIs on the other phones are turned off.


13



When a user dials the access code of a call group, phones of all members in the group ringsimultaneously. Members can pick up phones to join a meeting.

By default, the instant hotline service is enabled for call group members who can talk withspecific outer-group users after picking up phones. Members in a call group must beconfigured to the agent role. The call group service applies to highway scenarios.

When an outer-group user dials the group access code, all phones in the call group ring.After picking up their phones, call group members can directly talk with the outer-groupuser.

Call group specifications:

Item U1980/U1981 U1960 U1911

Maximum number of call groups 256 100 10

Maximum number of users in acall group

10 10 10


14



Typical Scenarios

[Scenario 1] An agent calls a call group

When an outer-group agent dials the group access code 83000, all phones(including 83001, 83002, and 83003) in the call group ring. Any member whopicks up a phone can talk with the agent. Phones that are not picked upcontinue ringing.

[Scenario 2] A call group member calls an agent

When call group member 83001 picks up a phone, the system automaticallycalls the outer-group agent and member 83001 hears a ringback tone.Member 83001 can talk with the outer-group agent who answers the call.

During the call between member 83001 and the outer-group agent, thesystem automatically calls the outer-group agent if member 83002 picks up aphone. Member 83001 hears a ringback tone and waits in the call queue. Theouter-group agent can check calls in the queue.

63



A single-node network is suitable for an enterprise with no more than 10,000 users thatdoes not have branches or has branches that do not require local regeneration. In such anetwork, the unified gateway and a variety of service servers are all deployed at theenterprise's equipment room, and all terminal users register with the unified gateway. Ifthe enterprise has small-sized branches, eSpace IADs can be deployed at branches andfunction as proxies for user registration to the unified gateway, or IP phones can bedeployed at branches and register with the unified gateway.

Networking Description

The unified gateway and a variety of service servers are deployed at the

headquarters.SIP terminals (including IP phones and SoftConsoles) register with the unifiedgateway. Analog phones and fax machines can directly connect to eSpaceU1911/U1960/U1980/U1981 through the ASI board thereon. They can also connectto eSpace IADs, and register with the unified gateway as SIP users through theconnected eSpace IADs that function as proxies for user registration.

The unified gateway can connect to the PSTN through trunks such as PRA, SS7,QSIG, R2, BRI, and AT0.


64



Service servers, such as the UMS (for the unified messaging service), CDRServer (forthe CDR service), ConsoleServer (for the console service), and Audio Recorder (forthe recording service), can be deployed based on service requirements.

The ECS software can be deployed to obtain ECS value-added services such as IM,group, and multimedia conferencing. UC soft terminals send registration andauthentication requests to the eServer for registration and authentication.

The built-in VMS of the unified gateway and the UMS have overlapping services.Customers can deploy either the VMS or USM based on their voice mailbox servicerequirements.

eSight centrally manages eSpace U1911/U1960/U1980/U1981, eSpace IAD and IPPhone.


65



A centralized call management network can be used for an enterprise with no more than10,000 users that has branches that require local regeneration. In such a network, theunified gateway functioning as the central node and a variety of service servers are alldeployed at an enterprise's equipment room, and all terminal users register with thecentral node in normal conditions. Unified gateways functioning as branch nodes aredeployed at the branches for local outgoing calls and local regeneration.


66



A distributed call management network in peer-to-peer mode can be used for enterpriseswith 10,000-30,000 users. In such a network, two or three nodes each deploy a unifiedgateway, which provides call services for the corresponding node. Different nodes areconnected using SIP trunks, through which inter-node calls are routed.


Each node has a unified gateway deployed. The unified gateway at a node is a voicegateway, which is responsible for user registration, intra-office users, and local PSTNcalls at that node. Different nodes are connected using SIP trunks, through whichinter-node calls are routed. The unified gateways can be eSpace U1911, U1960,

U1980, or U1981.IP phones, SoftConsole users (SIP users), UC soft terminal users (SIP users), andeSpace IADs (on behalf of analog phones and fax machines) at a node register withthe unified gateway at the node.

The unified gateways at different nodes can connect to the PSTN using trunks suchas PRA, SS7, QSIG, R2, BRI, and AT0 for local outgoing calls.


67



Enterprises with more than 30,000 users can use a distributed call management networkwhere four or more unified gateways are convergent.


Each node has a unified gateway deployed. The unified gateway at a node is a voicegateway, which is responsible for user registration, intra-office users, and local PSTNcalls at that node. A voice gateway can be eSpace U1911, U1960, U1980, orU1981.

IP phones, SoftConsole users (SIP users), UC soft terminal users (SIP users), andeSpace IADs (on behalf of analog phones and fax machines) at a node register withthe voice gateway at the node.

The voice gateways at different nodes can connect to the PSTN using trunks such asPRA, SS7, QSIG, R2, BRI, and AT0 for local outgoing calls.


68




69



Voice Communication

The unified gateway supports basic voice communication, including: Intra-officecommunication Intra-office users under the U1980 unified gateway can use varioussupported narrowband terminals to make voice calls to each other.

Narrowband trunk-based communication The U1980 unified gateway connects tothe PSTN or TDM PBX through digital trunks or analog trunk such as PRA, R2, SS7(ISUP/TUP), Q Signaling (QSIG). SS7 is short for signaling system No. 7, ISUP forintegrated services digital network user part, and TUP for telephone user part. Userscan make voice calls and receive incoming calls based on narrowband trunks.

Broadband trunk-based communication The U1980 unified gateway uses the SIPtrunk to connect to the IP PBX, softswitch, or IMS. Voice calls can be made betweenintra-office users and the users under other devices.


70



Instant MessagingP2P IM The P2P IM services allow two users to send IMs, transfer files, and sendSMS messages with each other

Temporary Group IM An enterprise user can select multiple contacts to create atemporary group on eSpace Desktop. Contacts in the temporary group can send IMsin the group's IM window.Contact Group IM An enterprise user can create and manage contact groups. Acontact group member can send IMs in the contact group IM window, and all theother members in the group can receive the IMs.

P2P File Transfer Files can be transferred between eSpace Desktops. A user candrag a file to the IM window of eSpace Desktop for file transfer.

Group ServiceContact Group A user can create a contact group on his or her UC soft terminal,and invite others to this group. The user who creates the group is the groupadministrator. Others can accept or reject the invitation.Temporary Group A user can create a temporary group and invite relatedpersonnel to the group for discussion. A user in the temporary group can sendgroup IMs, view the status of others in the group, and start instant conferences withall group members.

Presence

UC soft terminals (eSpace Desktop, eSpace Mobile, and eSpace Mobile HD) displaythe terminal status and information of enterprise users. Users can set their terminalstatus for others to learn about their working status.


71



Multimedia Conferencing


Conference scheduling: A convener schedules a conference beforehand using aweb-based self-service system. If the web-based self-service system is unavailable,the convener asks the enterprise administrator to schedule a conference.

Ways of joining multimedia conferences: 1) Users can dial the conference accesscode and join a conference as prompted or click the link in the conferencenotification email. 2) Users accept the conference invitation sent by the conferencemoderator to join a conference. 3) eSpace Desktop users can click the conferenceaccess shortcut and perform related operations as prompted to join a conference.


72




73



Two-Node Cluster and Clustering

eSpace UC solution supports two-node clusters for core gateways, some serviceservers, and some databases. When the active node in a two-node cluster fails dueto a hardware or network fault, the standby node automatically takes over services.In addition, eSpace UC solution supports clustering of eServers, MAAs, MeetingMSs, and recording servers.

Local Regeneration

When the active and standby nodes are both faulty or network connectivity is lostbetween the headquarters and branches, users at the branches fail to register withthe headquarter gateways. At that time, the branch nodes can use the localregeneration function to provide basic telephony services for local IP and analogphone users.

Users' dialing rules remain unchanged, but inter-branch calling using short numbersis unavailable. To call an internal user at another branch, others can dial the PSTNnumber of this user for connecting to this user through the PSTN.


74



SBC An enterprise may have multiple networks that are isolated from each other, and UCterminals and the UC system (that is, UC servers) of the enterprise may be located ondifferent networks. As a result, UC terminals cannot directly connect to the UC system.When this occurs, you can use the SBC to function as the signaling proxy and mediaaggregation gateway to enable VoIP and data communication among the isolatednetworks.

The SBC mainly fulfills the following functions: Signaling proxy Works as the terminalregistration proxy gateway to register UC terminals with the SIP server.

Media aggregation Aggregates media for establishing sessions between two UC

terminals or between a UC terminal and the UC system on two isolated networks.Network Address Translation (NAT) traversal Provides the NAT traversal functionwhen SIP messages need to be traversed by NAT (only the ACME SBC provides thefunction).


75



eSpace U1911/U1960/U1980/U1981 generates CDRs for all users connected to it andsaves the CDRs to its CDR pool. The CDRServer obtains the CDRs from the CDR pool ofeSpace U1911/U1960/U1980/U1981, parses the CDRs to generate CDR files, and savethem in the local disk. A CDRServer can connect to a maximum of 255 eSpaceU1911/U1960/U1980/U1981s.

The BMU obtains call records from the CDRServer through an FTPS interface, andwrites the call records to the database.

The administrator can manage call records on the BMU, such as querying anddeleting call records.

Enterprise users can query their own call records on the BMU self-service platform.

The CDRServer allows a third-party billing system to obtain the CDRs through an FTPor FTPS interface.


76



The eSpace Audio Recorder uses the site recording mode, in which the eSpace AudioRecorder joins a call or conference as a participant to receive data for recording.

Recording a two-party call The eSpace Audio Recorder joins an ongoing two-partycall to establish a three-party conference. The eSpace Audio Recorder receives SIPand RTP streams in the conference for recording

Recording a conference During a voice conference, the moderator can enable therecording function. The eSpace Audio Recorder joins the conference as a participantand records the conference

211




212



eSpace U1911/U1960/U1980/U1981 supports networking for remote disaster recovery (orcalled geographic redundancy). Midsize and large enterprises with multiple branches canuse such networking for better reliability. When devices in one place are faulty, devices inanother place take over services to ensure service continuity.


213




214



Active/Standby redundancy Two unified gateways are deployed at the headquarters as the active and standbynodes. The active and standby nodes use a heartbeat mechanism to constantlycheck each other's status.

NOTE:The active and standby nodes must use the same unified gateway model.

When the active and standby nodes are running correctly, all users register with the activenode. The active node processes all user requests and synchronizes user registration andconfiguration data to the standby node in real time.

When the active node fails, the standby node takes over all services from the active nodeand processes all user requests.

If the trunk gateway is not deployed, the active and standby nodes both connect to thePSTN. When the active node fails, configurations are required on the PSTN to set up trunkchannels with the standby node, and the standby node then routes calls to the PSTNthrough trunks.

All service servers support active/standby switching of the gateways. This means these

service servers automatically connect to the standby node for service processing after aswitching from the active node to the standby node.


215




217



The switching has the following impacts: New services cannot be started for ongoing calls,for example, call hold.

Ongoing voice conferences are interrupted.

CDRs cannot be generated for ongoing calls or conferences.

Ongoing message services are interrupted.

237



The disaster recovery mechanism is described as follows:Two central nodes are deployed in two places, and each central node has oneunified gateway deployed. The two unified gateways work in active/standby mode,known as an active node and a standby node (the active and standby nodes mustuse the same gateway model). The active and standby nodes use a heartbeatmechanism to constantly check each other's status. The service servers are deployedat the central node where the active unified gateway resides.

When the active and standby nodes are running correctly, all users register with the

active node. The active node processes all user requests and synchronizes data tothe standby node in real time. At least 1 Mbit/s bandwidth must be reserved fordata synchronization, and the round trip time (RTT) must be shorter than 80 ms.

When the active node fails, the standby node takes over all services from the activenode and processes all user requests.

A trunk gateway can be deployed for connecting to the PSTN. If the trunk gatewayis not deployed, the active and standby nodes both connect to the PSTN. When theactive and standby nodes are running correctly, the active node routes calls to thePSTN through trunks. When the active node fails, the standby node routes calls tothe PSTN through trunks.

Multi-Node Centralized Network

243




244



Networking DescriptionThe unified gateway at the headquarters is the central node, which can be eSpaceU1911, U1960, U1980, or U1981. The central node supports two unified gatewaysworking in active/standby mode, known as the active node and standby node.

The unified gateway at a branch is the branch node, which can be eSpace U1911,U1960, U1980, or U1981.

The central node and branch nodes all connect to the PSTN using trunks such asPRA, SS7, QSIG, R2, BRI, and AT0. Two connection modes are available:

A trunk gateway is deployed at the headquarters for connecting to the PSTNand routes call to the PSTN using trunks. The trunk gateway connects to thecentral node using SIP trunks.

A trunk gateway is not deployed at the headquarters, but the central nodedirectly connects to the PSTN. If two unified gateways working inactive/standby mode are deployed as the central node, the active node andstandby node each connect to the PSTN using trunks.

The central node and branch nodes are connected using SIP trunks. They alsouse a heartbeat mechanism to constantly check each other's status.


245



When the central node is correctly connected to the branch nodes,All users at the headquarters and branches register with the central node.

Services are uniformly configured and managed on the central node, and thecentral node synchronizes data to branch nodes in real time.

All calls are processed by the central node. When a branch user places anoutgoing PSTN call, the central node analyzes the call and routes the call tothe local branch node, which then routes the call outside of the enterprise.

When the central node is faulty or disconnects from a branch node, users at thebranch register with the branch node, and the branch node processes servicerequests from users at the branch. This is known as local regeneration.

Basic call functions for analog users at the branch node are not affected.

IP phones at the branch fail to register with the central node, and thenautomatically switch to the branch node for registration. Basic call functionsfor SIP users are not affected.

An PBX checks the validity of a dialed number and connects or rejects the call based onthe call prefix. A call can be connected correctly only if the call matches the correct callprefix. Therefore, a correct call prefix configuration is the key to the call service. A callmust match at least one call prefix


309



Short Number and Long Number

A short number is an internal number of an enterprise, and a long number isallocated by the carrier to an enterprise. Internal users of an enterprise can dial theshort numbers of each other. External users need to dial the long number of theenterprise.

VRP Introduction and Operation

315




317



Versatile Routing Platform (VRP) is a network Operating System (OS) used by datacommunication products of Huawei. As the core engine of the software for Huawei productssuch as all series of routers, Ethernet switch, and service gateway, VRP provides a uniformuser interface and management interface, including the real-time OS core, IP soft-forwardingengine, route processing and configuration management planes. It provides the function ofcontrol plane, and specifies the standard for forwarding plane interface, implementing theinteraction between the forwarding plane of products and the control plane of VRP. At thesame time, VRP provides network layer interface to interconnect the link layer to thenetwork layer.

This login password can be modified under the user-interface con 0 view, using command:set authentication password.

Under this view, command authentication-mode aaa is used to set user + passwordauthentication.


321



The router's commands are classified into a maximum of 16 levels.

By default, the commands are classified into four levels:

Visit level. The commands include diagnostic tools, such as the ping and tracertcommands, and the commands that are used to access a remote device such asTelnet.

Monitoring level. The commands are used for system maintenance, such as displaycommands.

Configuration level. The commands are used for service configuration, includingrouting commands and commands at each network layer, to provide networkservices to users.

Management level. The commands are used for basic system operations, includingfile system, FTP, Trivial File Transfer Protocol (TFTP), Xmodem download, andconfiguration file switching commands, slave board control commands, usermanagement commands, command level configuration commands, systemparameter configuration commands, and debugging commands.

If refined right management is required, command levels can be extended to 0 to 15.


322



Command line interfaces are classified into command line views. All commands must beexecuted in command line views. You can run a command only after you enter itscommand view.

# Connect to the switch. If the switch uses default settings, you enter the user view.

<Huawei>

# Enter system-view and press Enter to enter the system view.

<Huawei> system-view

[Huawei]

# Enter aaa in the system view to enter the AAA view.

[Huawei] aaa

[Huawei-aaa]

Note: The default sysname is Huawei. The prompt indicates the current view. For example,<> indicates the user view and [] indicates all other views except user view.

Some commands can be executed in multiple views, but they have different functions afterbeing executed in different views.


323



There are thousands of commands in VRP system, but users do not need to rememberthem all. But users must be familiar with some of the commonly used key commands.With the help system of VRP, users can complete configuration efficiently.


324



"aaa" and "password" are keywords. "AAA authentication" and "Authentication throughthe password of a user terminal interface" describe the keywords respectively.

<cr> indicates that there is no keyword or parameter in this position. You can press Enterto run this command.


325



INTEGER<1-35791> describes the value range of the parameter. The value of FTP timeout(in minutes) briefly describes the function of this parameter.


326



Enter the first several letters of a key word in the command and then press Tab to displaya complete key word. A complete keyword is displayed only if the partial string of lettersuniquely identifies a specific key word. If they do not identify a specific key work,continuing to press Tab will display different key words. You can select the needed keyword.


327



Error Message Example:

<Huawei>display xyz

^

Error: Unrecognized command found at '^' position.


328



The sysname command sets the device host name.

The undo sysname command restores the default device host name.

By default, the device host name is Huawei. But for some equipments, the defaulthost name may be Quidway.

Changing the host name affects the prompt of the command interface. For example,if the host name is Huawei, the prompt of the user interface is <Huawei>.

The display current-configuration command displays the currently running configuration.

The command does not display the default configuration.

If the output is more than 24 lines(default value), the output will be displayed morethan one page. Use <Enter> to display the next line, and use <Space> to display thenext page.


329



The display version command displays the version of the device.

You can use the display version command to view the version of the device todetermine whether the device needs to be upgraded.

And the uptime may indicate whether the device rebooted recently.


330



The display device command displays the type and status of the components on a device.

You can use this command to check the working status of components on a device,ensuring that the device is working normally.


331



The user-interface command displays one or multiple user interface views.

VTY Virtual Type Terminal user interface Manages and controls users that log into the device using Telnet or SSH.

The first one is VTY 0, the second one is VTY 1, and so forth.

The authentication-mode command configures the authentication mode for accessing theuser interface.

After you set the authentication mode for accessing a user interface to password,run the set authentication password command to configure an authenticationpassword. Keep the password safe. You need to enter the password when loggingin to the device. The levels of commands accessible to a user depends on the levelconfigured for the user interface to which the user logs in.

The set authentication password command configures a local authentication password.

Different products may require different password strength.

The user privilege command configures the user level.

By default, users who log in to the device using the console interface are atlevel 15 and other users are at level 0.


332



When the authentication mode is set to aaa, the authentication password is deleted at thesame time. Users are required to enter the login user name and password to log in to thedevice. After login, the level of the commands the user can run depends on the level of thelocal user specified in AAA configuration.


333



The interface command displays the interface view or sub-interface view.

Specifies the type and number of an interface. The interface type and number canbe closely next to each other or separated by a space character.

The ip address command configures an IP address for an interface.

The mask can be a mask in full format or the length of mask.


334



The display this command displays the running configuration in the current view.

After the configurations are complete in a certain view, runthe display this command to check the current configurations.

AR Voice Basic Operation and Configuration(Local Branch Scenario)

341




342




343




344




The unified gateway at the headquarters is the central node, which can be eSpaceU1911, U1960, U1900, or U1981. The central node supports two unified gatewaysworking in active/standby mode, known as the active node and standby node.





The central node and branch nodes are connected using SIP trunks. They also use a

heartbeat mechanism to constantly check each other's status.


345



When the central node is correctly connected to the branch nodes,

All users at the headquarters and branches register with the central node.

Services are uniformly configured and managed on the central node, and thecentral node synchronizes data to branch nodes in real time.

All calls are processed by the central node. When a branch user places anoutgoing PSTN call, the central node analyzes the call and routes the call tothe local branch node, which then routes the call outside of the enterprise.

When the central node is faulty or disconnects from a branch node, users at thebranch register with the branch node, and the branch node processes servicerequests from users at the branch. This is known as Local-survival.

Basic call functions for analog users at the branch node are not affected.

IP phones at the branch fail to register with the central node, and thenautomatically switch to the branch node for registration. Basic call functionsfor SIP users are not affected.


346




347



All calls are processed by the central node.


348




349



When configuring numbers on the primary node, you do not need to synchronize POTSphone numbers from the local node; however, you must configure a gateway ID (specifiedby localgateway id) for the numbers for authentication. If you add numbers of POTS usersbelonging to the local node on the primary node, you must set the number type to SIP;however, these numbers are configured as the POTS numbers with the proxy registrationfunction enabled on the local node. As a result, different types are configured for the samenumbers on the primary node and local node. Therefore, do not enable synchronization forPOTS numbers belonging to the local node on the primary node.

Registration process:

A POTS number corresponds to a specific port number on the user board on the localnode.

The local node uses a SIP registration proxy to register all POTS users with the primarynode.

On the primary node, registration IP addresses of the POTS numbers belonging to thelocal node are displayed as the IP address of the local node.

Call process:

When a POTS user makes a call as the calling party, the local node initiates a call forthe POTS user.

When a POTS user receives a call as the called party, the primary node learns that theIP address corresponding to the called number is the IP address of the local node, andforwards the call to the local node. The local node queries the port numbercorresponding to the called number on the user board and connects the call.


350




351




352




353




354



When the primary and local nodes are disconnected:

The local nodes automatically enable local survival and become independent IP PBXsfor SIP users to register with.

The status of users on local nodes is displayed as FAULT.

The basic call function is not affected for POTS users on local nodes.

When detecting that the primary node is disconnected, the local IAD automaticallysets the local node as the SIP server. The basic call function is not affected for SIPusers on the local node.

Configure call sources according to the data plan to implement the following requirements:

When a user at the central node dials 9 (outgoing call prefix) and a called number, thecall is routed through the central node. Users at the central node belong to the defaultcall source 0.

When a user at the central node dials 9 (outgoing call prefix) and a called number, thecall is outgoing to PSTN through the local node.

So we should configure two call sources for users at central node and local node.

5XXX belongs to the call source 0 it is default ,no need to be configured );

6XXX belongs to the call source 1;

Configure reroute analysis.

Configure the binding between call source and office route. When a user in call source1 dials outgoing call prefix 9 to make an outgoing call ,the call is rerouted to officeroute 1 (local node 1).

Multi-Node Distributed Network

387

A distributed call management network in peer-to-peer mode can be used for enterpriseswith 10,000-30,000 users. In such a network, two or three nodes each deploy a unifiedgateway, which provides call services for the corresponding node. Different nodes areconnected using SIP trunks, through which inter-node calls are routed.

This network applies only to the U1911/U1960/U1980/U1981.


Each node has a unified gateway deployed. The unified gateway at a node is a voicegateway, which is responsible for user registration, intra-office users, and local PSTN

calls at that node. Different nodes are connected using SIP trunks, through whichinter-node calls are routed.

IP phones, SoftConsole users (SIP users), UC soft terminal users (SIP users), andeSpace IADs (on behalf of analog phones and fax machines) at a node register withthe unified gateway at the node.

The unified gateways at different nodes can connect to the PSTN using trunks suchas PRA, SS7, QSIG, R2, BRI, and AT0 for local outgoing calls.

The BMU, eSight, and other related service servers are deployed at the headquarters

for centrally processing services.Service servers, such as the UMS (for the unified messaging service), CDRServer (forthe CDR service), ConsoleServer (for the console service), and Audio Recorder (forthe recording service), can be deployed based on service requirements.

This topic assumes the following number segments as the planned ones in the currentnetwork scenario:

Node 1: 80000 89999

Node 2: 60000 69999

Node 3: 70000 79999

In order to implement voice communication between different nodes, we need to configthe office route, prefix and sip trunk to other node on every node.

When the user 80001 dial 70001, the node 1 do the number analysis and route thecall to node 2, and the node 2 connect it’s internal user 70001.

When the user 80001 dial 60001, the node 1 do the number analysis and route thecall to node 3, and the node 3 connect it’s internal user 60001.

Enterprises with more than 30,000 users can use a distributed call management network wherefour or more unified gateways are convergent.

This network applies only to the U1911/U1960/U1980/U1981.


Each node has a unified gateway deployed. The unified gateway at a node is a voicegateway, which is responsible for user registration, intra-office users, and local PSTN calls atthat node.

IP phones, SoftConsole users (SIP users), UC soft terminal users (SIP users), and IADs (onbehalf of analog phones and fax machines) at a node register with the voice gateway at thenode.

The voice gateways at different nodes can connect to the PSTN using trunks such as PRA,SS7, QSIG, R2, BRI, and AT0 for local outgoing calls.

The convergence gateways route inter-node calls. Different convergence gateways areconnected using SIP trunks, and each convergence gateway connects to different voicegateways also using SIP trunks. A convergence gateway can be U1980 or U1981.

Multiple convergence gateways can be deployed in active-standby or load balancing mode.

The BMU, eSight, and other related service servers are deployed at the headquarters for

centrally processing services.Service servers, such as the UMS (for the unified messaging service), CDRServer (for the CDRservice), ConsoleServer (for the console service), and Audio Recorder (for the recordingservice), can be deployed based on service requirements.


396



Service RequirementsUsers at different local nodes can call each other using "area code+short numbers".

Users within a local node can call each other using short numbers or "areacode+short numbers".

Dialing area code+short number: The area code here is the local area code,and the calling method is the same as that used for calling users at the othernodes.

Dialing a short number: Users within a local node can call each other bydirectly dialing the short numbers.


397




398



Note:The above tables not contains the data plan in the node 2 and 3, please plan thedata in node 2 and 3 refer node 1;

Before config the local prefix in the U1900, the U1900 force you to add the DDDand IDD prefix first, use it to prevent toll fraud, and the DDD and IDD prefix wedidn’t contain in the above table.


399



In this network scenario, user numbers at each node are in format of "area code+shortnumber".

To implement inter-node voice communication, configure required parameters at eachlocal node and the convergent node. Specifically, at each local node, configure officeroutes, outgoing prefixes, and SIP trunks to the convergent node; at the convergent node,also configure these parameters to each local node.

When user 01080001 dials 02170001, local node 1 analyzes the number andaccording to the analysis result (021 is the call prefix to the convergent node), routes

the call to the convergent node. The convergent node analyzes the number andaccording to the analysis result (021 is the call prefix to local node 2), routes the callto local node 2. Then, local node 2 connects the call to user 05718004.

When user 01080001 dials 02560001, local node 1 analyzes the number andaccording to the analysis result (025 is the call prefix to the convergent node), routesthe call to the convergent node. The convergent node analyzes the number andaccording to the analysis result (025 is the call prefix to local node 3), routes the callto local node 3. Then, local node 3 connects the call to user 02560001.

407



Toll Fraud Scenarios

Transfer by the automatic switchboard

As shown by line (1) in Figure, outer-office user B dials the automatic switchboard number ofthe company with U1900 unified gateway A deployed, and dials user C's number when hearingan announcement or a two-stage dialing tone. If the call is connected by the automaticswitchboard, user B is charged only for a local call, while the company must pay the toll callfee.

Transfer through a trunk

As shown by line (2) in Figure, outer-office user C dials the incoming prefix configured onU1900 unified gateway A, the outgoing prefix for making calls from U1900 unified gateway Ato U1900 unified gateway B, and a toll number in sequence to make a toll call. For example, if0 is the incoming prefix configured on U1900 unified gateway A, and 00 is the outgoing prefixfor making calls from U1900 unified gateway A to U1900 unified gateway B, user C can dial0+00+123456789 to make a call to toll number 123456789.

Unauthorized registration

As shown by line (3) in Figure 1, an authorized user who is registered with U1900 unifiedgateway B by impersonating a registered user makes a call to outer-office user D. The call iscompletely free of charge to the unauthorized user.

Misuse of call forwarding services

As shown by line (4) in Figure 1, user B illegally obtains the administrator account andpassword for logging to U1900 unified gateway A or user A's self-service account andpassword, and enables the call forwarding unconditional (CFU) service for user A with user C'snumber configured as the forwarded-to number. When user B makes a call to user A, the call isforwarded to user C regardless of user A's status. User B pays only the local call fee to getconnected to user C, while the company must pay the toll call fee.

You can configure multiple outgoing call rights for a trunk. By default, a trunk has thelocal call rights. If you want to forbid the outgoing call rights for trunk tandem callsthrough a trunk, you are advised to configure only the inter call right for the trunk so thatan outer-office user who makes an incoming call through the trunk cannot make a call toanother outer-office user. To allow an outer-office user who makes an incoming callthrough the trunk to make a local call, you can use the default setting. To allow an outer-office user who makes an incoming call through the trunk to make a national orinternational toll call, you must add the ddd or idd call right to the trunk.


413



For example, to allow users to dial only extension numbers whose length does not exceed4, you must change the extension number length to 4 in the automatic switchboard script.

In this configuration example, the following requirement needs to be met: Only users withIP addresses within the range of 10.10.10.10 to 10.10.10.20 are allowed to log in to theU1900 unified gateway.

config add trust loginip startip 10.10.10.10 endip 10.10.10.20

config trust loginip switch on

Notice:

If the whitelist function is enabled but no IP address is added to a whitelist or the

network between the device and the IP addresses in the whitelist is unavailable, youwill fail to log in to the device through the IP network. In this case, log in to thedevice using the serial port, run the config trust loginip switch off command todisable the whitelist function, modify the whitelisted IP addresses as required, andenable the whitelist function again.

Extranet Access of UC Terminals

424




425




426




427



An enterprise deploys a session border controller (SBC) to bridge the enterprise intranet,demilitarized zone (DMZ), and extranet. Enterprise users on the extranet can register withthe unified gateway on the enterprise intranet through the SBC (as a proxy). Aftersuccessful registration, enterprise users can work efficiently on the extranet as they do onthe intranet.


428



The SBC mainly fulfills the following functions:

Signaling proxy Works as the terminal registration proxy gateway to register UCterminals with the SIP server.

Media aggregation Aggregates media for establishing sessions between two UCterminals or between a UC terminal and the UC system on two isolated networks.

Network Address Translation (NAT) traversal Provides the NAT traversal functionwhen SIP messages need to be traversed by NAT (only the ACME SBC provides thefunction).


429




430




431




432




433




434




435




436



The following describes the authentication and registration principles of a UC terminal onthe extranet:

eSpace Desktop sends an authentication request to the eServer through the firewall.

The eServer sends the SBC's external IP address corresponding to the SIP server(which is the U1900 series unified gateway) back to eSpace Desktop through thefirewall.

eSpace Mobile or eSpace Mobile HD sends an authentication request to the MAA inthe DMZ through the firewall.

The MAA sends the SBC's external IP address corresponding to the SIP server backto eSpace Mobile or eSpace Mobile HD through the firewall.

A UC terminal sends a registration request to the SBC's external IP address.

The SBC, through the external SIP proxy registration port, forwards the registrationrequest to the internal SIP server for registration.


438




439




441




442




444



Prerequisites

You have configured the basic network settings for the SBC.

You have obtained the password for logging in to the SBC.

Background

When the SBC and the firewall are deployed in parallel, the intranet and extranet IPaddresses need to be configured for the SBC.

When the SBC is deployed behind the firewall, only the intranet (DMZ) IP addressneeds to be configured for the SBC.


445



eSpace Desktop, eSpace Mobile, or eSpace Mobile HD on the extranet sends a registrationrequest to the firewall's external IP address. The registration request contains the portnumber and the terminal's IP address. The firewall transparently transmits the registrationrequest to the service server on the intranet. Upon receiving the request, the service serverdetermines the area to which the UC terminal belongs according to the UC terminal's IPaddress, queries the server IP address of the corresponding service in the area, and returnsthe IP address to the UC terminal.

The BMU determines the area to which a terminal belongs according to the IP addressreported by the terminal. If a terminal does not belong to any area, the policy for thedefault area is used.

459



Functions of devices in a console system:

SoftConsole

Provides basic call functions as phones do, such as placing, answering, and holding

calls.Provides agent functions, such as showing busy, showing idle, and forwarding calls.

ConsoleServer

Saves information about agents.

Authenticates agents during their login.

Queues incoming calls, maintains such queues, and updates queue information toeach SoftConsole.

Unified gateway

Handles SIP user registration of the SoftConsole.

Connects calls between agents and users.

If a user attempts to log in to the SoftConsole, the ConsoleServer first authenticates theuser. After the user is successfully authenticated, the user is registered with the unifiedgateway.

When a user dials a SoftConsole group access code, the unified gateway routes the call toan idle agent in the group who will then answer the call. If all agents in the group arebusy, the system queues incoming calls. When one or more agents become available, thesystem routes the calls to the idle agent(s) following the "first-come, first-served" policy.

Notice

A SoftConsole group access code is a hotline number provided by an enterprise, bydialing which users can be routed to agents.


460




461



Enterprise A releases the SoftConsole hotline 28887890 which is used to process internaland external calls.

Enterprise A poses the following requirements on the SoftConsole:

A SoftConsole group, including three agents, must be configured.

The supervisor can forcibly release and barge into agents' calls.

In the eSpace UC solution, the U1900 series unified gateways works with the CDRServer togenerate call detail records (CDRs) for the Business Management Unit (BMU) or a third-party billing system to obtain. The CDR system consists of the unified gateway andCDRServer. The U1900 series unified gateways generates CDRs for all users connected to itand saves the CDRs to its CDR pool. The CDRServer obtains the CDRs, parses the CDRs togenerate CDR files, and saves them to the local disk.

Functions of devices in a CDR system:

Unified gateway: Generates CDRs for all users connected to it and saves the CDRs toits CDR pool. The unified gateway periodically pushes CDRs to the CDRServer in anunsolicited manner or upon receiving the CDRServer's request.

CDRServer: Parses the obtained CDRs and stores them as binary files ( .bill) to aspecific location on the CDRServer. The CDRServer can proactively send a request tothe unified gateway for obtaining CDRs after CDR transfer is enabled under CDRConsole > Call record transfer switch of the CDRServer.

BMU: Obtains call records from the CDRServer through an FTPS interface, and writesthe CDRs into the database. The administrator can manage CDRs on the BMU, suchas querying and deleting CDRs. Enterprise users can query their own CDRs on theBMU self-service platform.

Third-party billing system: Obtains CDR files from the CDRServer through an FTP orFTPS interface.
