GSM codec in MGCP controlled Gateway from PGW 2200

Hi everybody.

Currently we are performing a test using PGW 2200 to integrate a SIP server with PSTN. We control an AS5300 mediagateway through MGCP version 1.0.

I would like to know if it is possible that the SIP User Agents use GSM to encode the voice calls, which are established against the MGCP controlled MediaGateway. I have tried the whole steps mentioned to setup the codec selection within PGW with no success. (I followed the steps from Media Gateway Controller Dial Plan Guide).

Thanks in advance for all your help and attention.
