Specifically, look at mod_com_g729 or Sangoma cards for g729 transcoding support.

You can then set your profile to allow G711 on incoming calls and specify G729 on outgoing calls either on the profile or using the absolute_codec_string variable. FS will then convert between the two for you.

Free versions of g729 are not available unfortunately, for patent licensing reasons.

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
