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.<br>the digium lib is much better. if you have more than 30~60 phones transcoding inst a very good idea.<br>
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.<br><br>the digium transcoder is GREATE 0 cpu was gone for transcoding.<br><br>keep this in mind.<br>

</div>Install the G.729 sound files and make app_voicemail record messages<br>
(format=g729) in G729. As long as you don't need meetme or a few<br>
other apps that essentially require G.729 transcoding you don't need a<br>
license.<br>
