6608 MTP Transcoder codec, G.729 Annex B

Does anyone know how to disable use of G.729 annex B (g729br8) codec for transcoding?

Have a remote site (MGCP GW) and calls are G729 across WAN and it is using G729br8 (Annex B w/VAD - silence suppression) which is a issue now and then and want it to be g729r8.

Have the CCM Service parameter strip g.729 annex b capability set to true on all servers already and have reset the transcoder and gateway and no change. This worked for other MGCP gateways and calls that aren't getting transcoded.

This is on a CCM 4.0(2a) system.

Hi Erick,

The CCM service parameter should do the trick,

I remember an old DDTS in which CCM Service Parameters wasnt working at all and a CCM.exe restart was necessary, which load the 6608 has?

Re: 6608 MTP Transcoder codec, G.729 Annex B

6608 load is M00104000003

Also, Silence Suppression service parameter is false.
