What codec is that using. 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...

Hi Cosmin<br><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><a href="http://www.asteriskguru.com/tools/bandwidth_calculator.php">
