G.729 will give you 10 calls at best over 256k unless you're trunking with
IAX2? I don't know anyone using lpc10...<br>
<br>
Remember a G.729 8k codec turns into 23.63 Kbps with all the overheads... <br>

You should be able to get about 12 simultaneous calls on a 128k line and<br>
about 28 on a 256k line according to asteriskguru's bandwidth calculator<br>
