In your case both the 6608 and the phone support g.729 so that is what CUCM is negotiating. Since you can't disable g.729 support on the phone you would need to somehow route the call through and intermediate device that only supports ilbc (for the phone leg) and then engage a transcoder to convert the ilbc to g.711 going to the 6608.<div><br></div><div>Remember the Region setting is just the max bandwidth for calls. Any codec less than (or equal to) the max and supported by all parties will be allowed.</div><div><br><div>
