CCME 4.1 integrate with CCM 4.2 as a h.323 gateway. Need to use g.729 for inter-site voip calls and g.711 for calls within local subnet. Now I configure a different region for CCME and choose codec g.729 to CCM region. Transcoder is configured only in CCME. Two sites can ring each other, but call drops as soon as it is picked up.
Should transcoder be configured in both CCM and CCME?
Should DSP resource for transcoder be available in both site gateways?
If inter-region codec is g.729, what is the codec with RTP streams sent from IP phone? Is the codec always g.711 with RTP streams sent from IP phone?
