Call Control
SIP IPv6 Calls Fail When Using UDP
Cisco Unified Communications Manager does not support SIP IPv6 signaling over UDP where the MTU is greater than 1500. To ensure that calls do not fail, change the transport protocol to TCP.
New Cisco Gateway Support
New releases of Unified Communications Manager have introduced support for the following Cisco gateways:
-
Cisco VG400 Analog Voice Gateway

The following table lists supported gateway models and the initial release, by release category, where support was introduced. Within each release category (e.g., 10.5(2), 11.5(x)), support for the gateway model is added as of the specified release, along with later releases in that category. For these releases, you can select the gateway in the Gateway Configuration window of Cisco Unified Communications Manager.
