2 Architecture
The MiaRec call recording system utilizes Built-in-Bridge call monitoring and recording capability
available in 3rd generation of Cisco phones. When call is started, Cisco UCM sends to MiaRec
recording server the metadata, which contains information about recorded call such as
participating device names, directory numbers, and cluster IDs. At the same time Cisco UCM
instructs IP phone to fork media data to the MiaRec recording server.

3 Requirements
The features utilized in this method of recording require the following:
1) 3rd generation phones that have the built-in bridge capability (BIB) *
2) Cisco Unified Communications Manager v.8.5 or newer
* - The list of phones that support the monitoring and recording features varies per version and
device pack. If you have any questions, consult your Cisco account management team to
determine if your telephone sets have this capability.

steps:
1. Start Cisco Unified Reporting by using any of the methods that follow:
a. Choosing Cisco Unified Reporting in the Navigation menu in Cisco Unified
Communications Manager Administration and clicking Go.
b. Choosing File > Cisco Unified Reporting at the Cisco Unified Real Time
Monitoring Tool (RTMT) menu.
c. Entering https://<server-name-or-IP-address>:8443/cucreports/ and then entering
your authorized username and password.
2. Click System Reports in the navigation bar.
3. In the list of reports that displays in the left column, click the Unified CM Phone Feature
List option.
4. Click the Generate a new report link to generate a new report, or click the Unified CM
Phone Feature List link if a report already exists.
5. To generate a report of all devices that support recording, choose these settings from the
respective drop-down list boxes and click the Submit button:
a. Product: All
b. Feature: Record
6. The List Features pane displays a list of all devices that support the recording feature. You
can click on the Up and Down arrows next to the column headers (Product or Protocol)
to sort the list.

Revision 1.1 9
You can check the Deliver Conference Bridge Identifier check box, which delivers additional
information (specifically, the b-number that identifies a conference bridge) to the recorder across
the SIP trunk. If the check box is left unchecked, the far-end information for the remote
conference remains empty. Check the Deliver Conference Bridge Identifier check box on the
remote cluster SIP profile as well. Checking this check box is not required for recording, but the
conference bridge identifier helps to update the recorder when recording calls that involve a
conference bridge.

Revision 1.1 10
5.2 Create SIP Trunk Security profile
Use the System > Security Profile > SIP Profile menu option in Cisco Unified Communications
Manager Administration to create SIP Trunk Security profile for recorder.
Set Incoming Transport Type to TCP+UDP.
Set Outgoing Transport Type to TCP (this setting has to match the configuration of
MiaRec). TCP is recommended.
Uncheck option Enable Digest Authentication
Set Device Security Mode parameter to Non Secure.

Revision 1.1 11
5.3 Create a SIP trunk that points to the recorder
Use the Device > Trunk menu option in Cisco Unified Communications Manager Administration
to create SIP trunk that points to the recorder.
In SIP Information section configure:
Destination Address should point to ip-address or DNS name of the recorder server
Destination Port should match the port on which MiaRec recorder is listening for
messages from CUCM (see configuration of MiaRec below)
Select the previously created SIP Trunk Security Profile for the recorder
Select the previously created SIP Profile for the recorder

5.4 Create recording profile
Use the Device > Device Settings > Recording Profile menu option in Cisco Unified
Communications Manager Administration to create recording profile.
The following figure illustrates creating a recording profile.
Set Recording Destination Address to the directory number that associates the recorder with
this recording profile. The only guideline for this number: it should be possible for UCM to route it
to the SIP trunk where the recorder is defined. No user is going to directly call this number, this is
internal to the system. Make sure it does not collide with your numbering plan. This is why the
example shows '7777'.

Revision 1.1 13
5.5 Create a route pattern for the recorder
Use the Call Routing > Route/Hunt > Route Pattern menu option in Cisco Unified
Communications Manager Administration to create a route pattern for the recorder SIP trunk:
Route Pattern should match to the Recording Destination Address in the previously
created recording profile
In Gateway/Route List select the SIP trunk that points to the recorder, or select a route
list of which the recorder is a member

5.6 Enable Built-in-Bridge for all phones (optional)
Built-in-Bridge setting can be enabled on per-phone basis or on system level (default to all
phones).
Use the Access System > Service Parameters menu option in Cisco Unified Communications
Manager Administration to enable Built-in-Bridge on system level.
Change the following option:
Clusterwide Parameters (Device - Phone) -> Built-in Bridge Enable

5.7 Configure tones for Recording
Set the service parameters for playing tone to True to allow tone to be played either to agent
only, to customer only, or to both.
Use the System > Service Parameters menu option in Cisco Unified Communications Manager
Administration to perform the necessary configuration.
Change corresponding options of group Clusterwide Parameters (Feature – Call Recording).
The following figure illustrates using service parameters to configure tones.

Revision 1.1 16
5.8 Codecs configuration
Codecs iLBC, iSAC, L16 and AAC-LD should be disabled for Recording-Enabled devices as they are
not supported by MiaRec recording system at the moment.
Use the System > Service Parameters menu option in Cisco Unified Communications Manager
Administration to perform the necessary configuration.
Change the following settings of group Clusterwide Parameters (System - Location and
Region):
“iLBC Codec Enabled” to “Enabled for All Devices Except Recording-Enabled
Devices”
“iSAC Codec Enabled” to “Enabled for All Devices Except Recording-Enabled
Devices”
“Default Intraregion Max Audio Bit Rate” to “64 kbps (G.722, G.711)”
If recording of conference calls is necessary, then G.722 codec should be disabled also for
Recording-Enabled devices. Our product supports G.722 codec, but this codec is not supported by
Cisco Conference Bridge and because of this limitation, call recording of conferenced calls is not
possible. Change the following setting:
“G.722 Codec Enabled” to “Enabled for All Devices Except Recording-Enabled
Devices”
MiaRec Cisco Buit-in-Bridge Configuration Guide
Revision 1.1 17
Verify Region Configuration under menu System > Region.
Per-region setting “Max Audio Bit Rate” should be set to either “Use System Default” or as
“64 kbps (G.722, G.711)” as shown on below screenshot.

7.3 Public IP Address
Specify public IP address if MiaRec server is located behind NAT. Make sure that port forwarding is
configured properly on your NAT router. If MiaRec server is not behind NAT, then leave this
parameter empty.
7.4 UDP Ports Range for RTP Media Data
If necessary, change default values of “Begin RTP port range” and “End RTP port range”.
Make sure that the port range is large enough for anticipated number of concurrently recorded
calls. One concurrent call requires two UDP ports for receiving media streams from agent’s phone.
