Didn't read the whole thread but make sure CIPC doesn't have "Optimize for low bandwidth" checked in the preferences.  This tries to force G.729.

Regions are important for a working call flow, yes.  However, regions only exist on CUCM, not on gateways.

The way in which regions/codec selection could produce the issue your seeing is as follows:

Dial Peer has g711ulaw on it
CUCM SIP Trunk has Gateway-Region on it
CIPC has Phone-Region on it
Gateway-Region to Phone-Region is using 8kbps

Region is not define in the config but CUCM. Is that what you need? That is the only config I have. and don't see any region defined in the gateway.

thanks

But you didn't send all the information, because your output doesn't show the dial-peers.

One method is to capture the output from "debug voip ccapi inout" and look for the following line "Outgoing Dial-peer="

You also didn't address the regions either.  Can you send that too?

I was just trying to give you all the information so that you will be able to see the whole picture.

Regarding your questions, I don't know how to check that.

That's interesting that I asked for the dial-peer config, and you sent everything but.

Do you know how to confirm which dial-peer the gateway is using?
