[cisco-voip] Using g729r8 instead of g729br8

[Erick Bergquist]

Hi,  I am trying to get calls coming in a remote MGCP gateway to use g729r8 across WAN instead of g729br8 when a 6608 MTP Transcoder is being used. The regions in CCM are set to use G729 between them, and I have tried setting the CCM service parameter to strip G729 Annex B from codec to true and reset the MGCP gateway and 6608 to no effect.  Silence suppression parameters are set to false also.

All the documentation on the 6608 transcoding I read saids G711, G729, or G723 but it doesn't mention which G729 flavors it supports. The documents for IOS transcoders list the different flavors, but there is also codec configuration you can do on the router/gateway and tell it which to use unlike the 6608. 

Any know how to kill the VAD / silence suppression on g729 with this setup? 

Thanks, Erick
