In Market

* Formal certification pending

ScalabilityHybrid Gateways

• Mediant 1000 Hybrid

– fractional E1/T1 interfaces (up to 16 channels), as well as 8 BRI (16 calls) and 16 FXO interfaces

• Mediant 2000 Hybrid

– Up to 4 E1/T1 (120 concurrent RTA sessions)

Advanced Topologies

• Mediant 1000 is the only Gateway certified by Microsoft that supports E1/T1, BRI, FXO, FXO interfaces in a single 1U chassis– Can operate concurrently

– Same chassis supports various modules so customers can grow from FXO/BRI interfaces to E1/T1 interfaces without changing field equipment

• Facilitates deployments in advanced network topologies– Example (1) – Connecting to both OCS & Exchange at the same time

– Example (2) – Fax adapters for OCS

– Example (3) – Drop & Insert configuration

Advanced Topologies (1)OCS and Exchange in the same network

• AudioCodes gateways can simultaneously operate with OCS and Exchange

• Enables OpEx reduction by using a single gateway

• Enables PBX users and OCS users to connect to the Exchange Server and use the Unified Messaging capabilities

Advanced Topologies (2)Enabling Fax services on OCS

• OCS does not provide native support for connectivity of Fax machines

• AudioCodes gateways (Mediant 1000 and MediaPack) enable existing Fax machines at the enterprise to remain active

– Using the advanced dialing plans, it is possible to continue regular usage of the Faxes

Advanced Topologies (3) Using Gateways to reduce PSTN connections

• Connecting the PBX to the OCS requires a dedicated trunk for interfacing the gateway, and an additional trunk for preserving PSTN connectivity

• AudioCodes gateways enable connectivity in a“Drop and Insert” configuration eliminating the need for an additional costly trunk on the PBX

Advanced Gateway capabilities

• Native support for – PSTN to SIP mapping (PRI, CAS)

– SIP TLS , TCP

– sRTP

– Full SIP redundancy options

– Full load sharing options using DNS , SRV , round robin (also internal DNS tables)

– IPSec

– Multi VLAN option to separate management, control and Voice on different IP

address and VLAN

– Internal routing tables with alternative routing capabilities for complex network

scenarios

– Advanced digits manipulation for source and destination numbers

• Coming in the next release – Support for VLAN per trunk group (for Voice separation) – Highly important for hosted

solution

Advanced Gateway capabilities (2)

• Stand-Alone Survivability (SAS) for enabling continued SIP

phone service in case of WAN failure – SIP Phones register to SAS agent on AudioCodes

gateways

– In case of WAN failure, the SAS agent provides

basic dialing plan services until connection is restored

– Call to and from the PSTN are still available using the AudioCodes PSTN

interfaces

– Advanced dialing plans facilitate any type of call routing to be implemented

• EMS for managing a large distributed enterprise

deployment from a single IT operations center

IP to IP capabilities*

• Enabling connectivity of non-certified IP-PBX to OCS by

– Mapping SIP to SIP over TLS and TCP

– Converting RTP to SRTP

– Enabling

• Full SIP redundancy options

• Full load sharing options using

DNS , SRV , round robin

(also internal DNS tables)

– IPSec

– Internal routing tables with

alternative routing capabilities

for complex network scenarios

– Advanced digits manipulation

for source and destination numbers

• No “Hard coded” limitations

• Allows flexible translation and number normalization

– From and To E.164 numbering format into

the PBX / key system and the PSTN

Flexible Routing Tables

X

In case of PBX 1 failure, the Mediant automatically uses alternative route to send the call to another Mediant at location #2, and through there, out to the PSTN via the local PBX at location #2

Regular calls from location #1 go out to the PSTN

Flexible Routing Tables

X

In case of IP/Mediation/OCS failure, the Mediant automatically uses alternative route to re-route the call back to PBX

Regular calls from PSTN arrive to OCS user trough Mediant

Out-of-Box Configurability

• All parameters required to set up a network are web configurable using an intuitive GUI

• Gateways are shipped with specialized management screens for Microsoft Unified Communications, allowing quick and simple configuration*– Consolidates all the relevant parameters to step-by-step easy to follow

and intuitive screens
