Avaya TSAPI DMCC recording
3. Configure Avaya Communication Manager
This section presents configuration steps for the Avaya Communication Manager. It is assumed that an appropriate license file and authentication file have been installed on the server, and that login and password credentials are available.
The configuration and verification operations illustrated in this section were all performed using the Communication Manager System Administration Terminal (SAT).
The procedures include the following areas:
- Verify the status CTI link for TSAPI service
- Disable RTP encryption
- Enable RTCP reporting
- Disable IP-IP Direct Audio (optional)
- Administer System Parameters Features
3.1. Verify the status of CTI link for TSAPI service
Log into the System Access Terminal (SAT) to enter the "status aesvcs cti-link" command. The link status should show no for maintenance busy (Mnt Busy), the Service State should indicate established and Version should be 6 or higher.

If the CTI link is not established, then follow instructions in chapter Administering Communication Manager for AE Services in document Application Enablement Services Administration and Maintenance Guide available at http://support.avaya.com
3.2. Disable RTP encryption
Execute the "list ip-codec-set" command.

For each of codec sets, execute the "change ip-codec-set N" command, where N is an index of set (from 1 to 7 in above example).
For example, to edit the first codec set, execute the "change ip-codec-set 1" command and make certain that Media Encryption list contains only a single value "none". If other values are presented there (for example, "aes"), then remove all other values except "none" as shown below:

Repeat this step for all the remaining codec sets.
3.3. Enable RTCP reporting
Enter the "change ip-network-region N" command, where N is an existing network region used for the agents' ip phones and softphones. Make certain that the RTCP Reporting Enabled field is set to "y", as shown below. The RTCP packets are used by MiaRec to map IP addresses to agent extensions.

3.4. Disable IP-IP Direct Audio (optional)
You can skip this step if recording of internal calls between IP phones is not needed.
Avaya Communication Manager supports "shuffling" of the media streams, which allows two IP phones to send media directly between each other bypassing the media gateway. "Shuffling" (IP-IP Direct Audio) should be disabled when internal calls between IP phones need to be recorded. IP-IP Direct Audio can be disabled either for individual IP phones or for a whole ip network region.
To disable IP-IP Direct Audio for individual IP phone, enter the "change station xxxxx", where xxxxx is phone's extension and change "Direct IP-IP Audio Connections" to "n" on Page 2.
Parameter "IP Audio Harpinning" is recommended to set to "y". In this case, MedPro board acts as a proxy without allocating of resources on TDM bus.

To disable IP-IP Direct Audio for all IP phones inside the IP network region, enter the "change ip-network-region N" command, where N is an existing network region used for the agents' ip phones and softphones and change "Intra-region IP-IP Direct Audio" and "Inter-region IP-IP Direct Audio" to "no".
Parameter "IP Audio Hairpinning" is recommended to set to "y".

Alternatively, instead of changing "IP-IP Direct Audio" parameter, you can change port mirroring configuration and mirror each IP phone's port rather than CLAN and MedPro ports (see below network diagram).
Such configuration of port mirroring allows a recording of internal calls without changing of "IP-IP Direct Audio" parameter.
3.5. Administer System Parameters Features
Enter the "change system-parameters features" command. Navigate to Page 5, and verify that Create Universal Call ID (UCID) has value “y”. If not, then set it to "y" and set UCID Network Node ID to an unassigned node ID.
