Use network regions to group IP endpoints and VoIP and signaling resources that share the same characteristics. Signaling resources includes Avaya Aura® Media Server and PROCR. In this context, IP endpoint refers to IP stations, IP trunks, and G430 and G450 branch gateways. These IP endpoints and resources have the following characteristics:
Audio Parameters
Codec Set
UDP port Range
Direct IP-IP connections
Hairpinning
H.323 security profile
TLS service
Signaling channel encryption
TTS service
Registration and reregistration process
Important:
Communication Manager uses TLS to encrypt the signaling channel between Communication Manager and 96x1 H.323 phones. It also uses TTS for fast registration and reregistration process.
