In the IP Network Region form, the Authoritative Domain field is configured to match the
domain name configured on Session Manager. In this configuration, the domain name is
avaya.com. By default, IP-IP Direct Audio (shuffling) is enabled to allow audio traffic to be
sent directly between IP endpoints without using media resources in the Avaya G650 Media
Gateway. The IP Network Region form also specifies the IP Codec Set to be used for calls
routed over the SIP trunk to Session Manager. This codec set is used when its corresponding
network region (i.e., IP Network Region „1‟) is specified in the SIP signaling group.
