codec payload for IP Phone

Can the payload of the codec on an IP Phone changed like it can on an H.323 gateway. If not what is the impact of a gateway with a 40 byte g729 codec rather than the standard 20 byte payload?

Re: codec payload for IP Phone

Yes You can.

Do next - login to CCM server.

After that go Service->Service Parameters.

Select a CCM server.

At the left side You will see Services, select "Cisco CallManager" Service.

You are at the Service Parameters Configuration Menu.

Go down to the next parameters:

PreferredG711MillisecondPacketSize

PreferredG723MillisecondPacketSize

PreferredG729MillisecondPacketSize

Change them as You wish.
