Use the command change ip-codec-set x (where x is the codec-set number) to configure IP
codec(s). The following screens show the codec configuration. IP-codec-set 1 uses G.711MU
and ip-codec-set 2 uses G.729.

3.3. Configuring Signaling and Trunk Groups to Cisco 2811
Gatekeeper
In order to configure Avaya Communication Manager as an H.323 Gatekeeper to send LRQ to
the Cisco 2811 GK, a signaling group for outbound traffic must be configured. Note that the IP
address of the Avaya S8300 Server (procr) functions as an IP address for both H.323 GW and
GK.
Use the command add signaling-group <group number> to create a signaling group. The Near-
End Node Name and Far-end Node Name are configured to the procr and Cisco-GK
respectively. To configure the Avaya S8300 Server as a H.323 GK, LRQ required must be set to
y. Near-end Listen Port and Far-end Listen Port must be configured to 1719 (UDP port 1719 for
H.225 RAS). Direct IP-IP Audio Connections and IP Audio Hairpinning must be set to n for
successful media paths. Disabling Direct IP-IP and IP Audio hairpinning will establish the RTP
stream between the G350 Media Gateway and the Cisco IP Telephones for inter location calls.
To support out-of-band DTMF, DTMF over IP must be configured to out-of-band. To control
Codec Set selection, the Far-end Network Region is configured to 2. Note that this signaling
group is configured to be associated with the trunk group 20.
