4.2. Inbound Signaling
All inbound traffic from Zone 2 to Zone 1 requires an additional Trunk and Signaling Group.
In this case, the Signaling Group’s Near-End IP address is set to the IP address of the CLAN at
port 1720, and the Far-End is unspecified.
The unspecified far-end signaling group is used for all incoming calls from Zone 2 to Zone 1.
The Avaya IP600 Server listens on Port 1720 to handle H.225 /Q.931 traffic.
4.2.1. Unspecified Signaling Group
The “Far-end Node Name” field is left blank, and it is necessary that “Direct IP-IP Audio
Connections” and “IP Audio Hairpinning” be set to “n” on this screen.
