When you set the codec for a region, you are not setting the only codec that can be used. You are setting the maximum codec that can be used. Since Cisco phones do not support g.728, the phones are negotiating and using a lower supported codec, g.729.
Thanks guys. this is really good information to me.
Got one more question:
If that's the case, I have one real scenario: my customer is running g726 for this: pbx-PRI-r0-g726(IP)-r1-PRI-PBX. They will integrate CCM into it with IP Phones.I do not see ccm supports g726. With your concept, can I make IP phones talk to PBX phone? CCM will use H323 to PBX gw. Thanks
If CM is connected to the 3rd Party PBX with a PRI in between, you dont need to do anything as long as the Router to which the PRI is connected is talking to the CM using G729/G711. If the 3rd Party PBX is connected to the CM through IP ONLY, then you will need a transcoder here.
