[asterisk-users] G729 Passthrough How To

[Eric Wieling]

If you want to do pass-thu you need to make sure Asterisk NEVER EVER needs to transcode.   This means all calls must use only g729, sound files must be in g729 format and no early audio, inband ringing or anything else which might cause Asterisk to require a temp transcoding path.

In my experience it never works right.    The most you should expect to be able to do is reduce the need for transcoding by doing the above steps.
