Re: Phones Change Codec

Have you tried disabling advertise G722 codec.

We had a similar problem and it was related to us using both a software and hardware conference bridge.

Hi,

The CFB is Cisco IOS Enhanced CFB, CUCM version is 6.1.3, the CFB is local to the site and there is only one CFB in the list.
