How do you disable G.729 codec in Unity 4.01?

We have been trying to troubleshoot transcoding resources and have had no luck. We think it is because the server is able to transcode to G.729a natively. In 4.01, there is no way to disable it that we have seen. Anyone have any input?

You can stop the TSP from advertising support for g.729 to CallManager by making this change:

HKEY_LOCAL_MACHINE\SOFTWARE\Active Voice\AvSkinny

from

"G729 Enabled"=dword:00000001

to

"G729 Enabled"=dword:00000000

and then rebooting. After that Unity will only report support for g.711ulaw to CallManager.

Hope that helps,

Cisco Unity Is G.729a Capable

When the registry setting HKEY_LOCAL_MACHINE\Software\Active Voice\AVSkinny\G729 Enabled is set to 1, it means that Cisco Unity is capable of receiving both G.729a streams and G.711 streams. It does not indicate that G.729a is in use for message storage. This is the default setting for Cisco Unity version 3.1(x) systems. Because the G.729a codec is installed automatically with version 4.0(1) and later, this registry setting is no longer needed

Although 4.0(1) does not require the registry key to be present you can still manually add it and set it to 0 to turn off g.729 support for the TSP.
