E1 uses G711... I'm assuming by saying that FS is acting as the gateway you're using something like mod_freetdm?
If so FS can transcode so that it uses G729 for the SIP side of the bridge.
Look at the commercial mod_com_g729 (licenses available for $10/channel on www.freeswitch.org).
You just need to have that loaded instead of mod_g729, and tweak your codec preferences accordingly.

Hi,
I just finished a freeswitch server that act as E1 gateway for PBX
system. I noticed that all the call from the gateway use PCMU codec
before transcoded to G729 in my main SIP server.
My current situation is as following :
[PBX] --- E1 ---> [Gateway] --- SIP/PCMU ---> [SIP Server] --- G729
---> [ITSP]
What I intended to do is as following :
[PBX] --- E1 ---> [Gateway] --- SIP/G729 ---> [SIP Server] --- G729
---> [ITSP]
Is there anyway to send the media from E1 gateway as G729 instead of
PCMU? I need to preserve bandwidth for future expansion.
Regards,
William
