[cisco-voip] G722 under MGCP PRI ?

[Jason Aarons (US)]

On my CME 7.1 H.323 Gateways it does G.722 from phone to gateway.  Wonder if maybe CME is transcoding.

I thought voice class codec was H323 only command.

Well if you are sending the call out the PRI, the PSTN will only support G.711.

My regions for this MGCP controlled PRI are for G.722.  Is there a way to enable G.722 on MGCP? All calls are going G.711 to gateway.
