to play a audio file in g729 and when a digit is pressed, the call
should switch to another codec (say ulaw). So, What can I do in the
extensions.conf to trigger a re-negotiation of codec?<br><br>I used <br>exten => 55xx,n,Set(SIP_CODEC=ulaw)<br><br>but, I suppose this affects the next call and not the current one.<br><br>Please help ASAP<br><br>Thanks,<br>Sai</div></div><br>
