[Freeswitch-users] Force G729 codec for E1 connection

[Steven Ayre]

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.
