I can place a call from IP phone (7962) to IP phone 7962 using iLbC and 7962 to IP Communicator 7 and I see I am using the iLBC codec on each end of the connection. I negotiate G729 when I use a gateway to reach the PSTN. Far as I can tell all is set up correctly with my regions, locations, device pools etc. Is iLBC supported in the following path between the phone and gateway?</div>
