How to ensure the Cisco UC560 uses only the Codec G.711 on all SIP trunkl phone calls

When calls are made using the SIP trunks the SIP invite from the Cisco UC agrees on the G7.11 codec, but when the RTP stream starts the call fails because G7.29 is being used.

How do i make sure the Cisco will only use the G7.11 codec all the way through the call?

That did not resolve the issue. Turned out to be with the Carrier so customer terminated contract with Carrier and installed a new PRI service.
