out there is a free for educational and no commercial G729 lib for asterisk you can use it to test in a non-comercial system. the digium lib is much better. if you have more than 30~60 phones transcoding inst a very good idea. i made my self a test on a core 2 duo 64 bits 2GB of ram a test transcoding more than 90 calls the sound quality was BAD not poor BAD.
the digium transcoder is GREATE 0 cpu was gone for transcoding. keep this in mind.
