Nortel Networks NN43001-121 manual Revision History, January, December

10New in this release

—SIP UPDATE method is not supported by Mediation Server. This method enables SIP Gateways and Endpoints to update the call information during a call. Because the OCS 2007 Mediation Server does not support UPDATE, re-INVITE’s need to be sent to the Mediation Server for every change in the call information during

a call. This has not changed since LCS 2005. There were no interoperability issues.

—G.711 codec for the short leg (Mediation Server to Communication Server 1000) and RT audio for the long leg of a call (Mediation Server to OCS) is supported.

•The Nortel Multimedia Convergence Manager (MCM) 3.0 is introduced in Converged Office. For more information, see "Multimedia Convergence Manager (MCM)" (page 28).

•OCS 2007 snap-in for MMC. For more information, see "OCS 2007 snap-in" (page 27).

•The 8540 OCS desk phone can register as an OC 2007 client, however, Microsoft does not support using a CS 1000 twin phone with them.
