[Freeswitch-users] media gateway

Hi is it possible to use freeswitch as media gateway in which freeswitch is used just for transcoding between g711u and g729? I need this to be able to use g729 codec available on linux because my main freeswitch box is based on windows(all registration info must be on this machine) and I've got a limited bandwidth to handle 10 concurrent calls so I need to have such thing call -> fs(windows)->g711->fs(linux)->g729->ip phones(7941) thanx
