Starting from Release 8.1.2, Avaya Device Adapter Snap-in supports both Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) for signaling within the Avaya Aura® deployment.
The signaling between Device Adapter and the endpoints still uses only IPv4 connection because the endpoints support only the IPv4.
The signaling between Device Adapter and Avaya Aura® components can be IPv4 or IPv6.
Device Adapter uses the IP version that a server negotiates as the preferable version. The Device Adapter determines which IP version to use based on the data received from Avaya Aura® System Manager and Avaya Breeze® platform. When both sides of a connection, for example, Avaya Breeze® platform and Session Manager support IPv4 and IPv6, Device Adapter makes the decision according to the IP address family preference service attribute.
The following servers can use IPv6 with Device Adapter:
-
Avaya Aura® System Manager (SMGR)
-
Avaya Aura® Session Manager (SM)
-
Personal Profile Manager (PPM)
-
Avaya Aura® Device Services (AADS)
-
Survivability server
