G729 issues using the CCM 3.2 and H323 Gateway

Hi,

I have a CCM 3.2 SPG version and i m using a G729 codec for inter-cluster callmanager.

With this codec, i cannot use these differents functions:

1. Transfer

2. Conference call.

Any comments ?

Re: G729 issues using the CCM 3.2 and H323 Gateway

I'm going to assume you are using MoH during transfer. By default in 3.2, the IP Voice Media Streaming App does not have the G.729 codec selected for MoH. Go to Service Parameters, IP Voice Media Streaming App and make sure G.711 and G.729 are both selected for all CallManagers in both clusters. You may need to restart the service.

Also, I'm going to assume that you are using the SW Conference bridge supplied with CallManager. These do not support G.729 - you must have a hardware transcoder availble (6608, HDV-FARM etc.).

Hope this helps,

Justin.
