This is because it is the "best quality" CODEC that can be negotiated. So, as long as you have the G722 CODEC enabled in the Call Manager service parameter, have enabled G.722 advertisement in the Enterprise Parameters, and have phones that are allowed to advertise G.722 - then you will find that two G722-capable phones that are talking to each other in a G.711 region will actually use G.722. Now, G.722 has the same bandwidth requirements that G.711 has. When this CODEC is specified and the inter-region Link Loss Type is set to “lossy” the iLBC CODEC is forced. This setting identifies the best quality (highest bandwidth) CODEC that can be negotiated.

Not sure how this plays with X-Lite as a client, but it may mean you will need to set a preference on CODEC choices. Also, with respect to SIP trunks, CUCM relies on the CODEC preferences in the SDP provided by the SIP-UA. It doesn't have an immediate impact on your scenario, but it is something to keep in mind. 4.9.3 not fully supported) Skype for Business Version 5.8.0.945 to 7.5.8.501 (for consumer) Other. It is a subtle difference, but a difference nonetheless. The software update mechanism enables you to get the latest firmware for all devices and keep them updated for. Keep in mind that when CUCM refers to the audio CODEC they really mean the "best CODEC" not the "only CODEC supported". You only other alternative is to put X-Lite in a special device pool which has a special region that allows inter-region use of the G.711 CODEC. If you go with the X-Lite pro, you can get the G.729 CODEC supported in the client and then you should be able complete your calls successfully. In other words, your calls are failing for the reasons you have already identified.
