Change codec for SIP from G729 to G711

[chinroc]

We have customer who is running on SIP trunk. Right now they are using codec G729. But I want to know how can we change this codec from G729 to G711? What licenses they require? System is 3300 CXi and version is 8.0.8.8.

I'm not really sure you can turn off G.729 on a SIP call without having the carrier do it.
On an incoming call the carrier will request G.729. If the call is going directly to a phone it will set the call up at G729 - no license required. If the call is going to the embedded VM or an analog device the call will require a license and a DSP. Without them, it will set up at G711.

Why do you want to turn of G729 to a phone?

Upgrade the controller and enable "Renegotiate SDP to enforce symmetric code" in the SIP Peer profile.

Knowledge is power, thats why we share!

Becareful for asking for G711, we have just been required to use G729 for all communication with our SIP providor AT&T. I have yet to receive confirmation from this, but we have lost features due to this. No more MOH outbound, only internal works. According to AT&T we may lose other features in the near future if we don't switch. Good luck.. I have a post going about it already if you care to read further.
