Hi Richard,<br><br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"><div class="im">
<br>
</div>There is no event for Asterisk to recognize. The PROGRESS message just<br>
says that there is an audio message available for the caller to listen<br>
to. Asterisk just passes the indication to the peer channel and opens<br>
the audio path. It is the caller who must recognize any audio message<br>
that their call has been dropped. </blockquote><div><br>Thanks for the explanation. Any suggestion on how to recognise that the call has been dropped?<br><br><br>--<br>Thanks,<br>Ishwar.<br><br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
As far as ISDN is concerned, the<br>
call has not been answered yet so Asterisk must keep waiting.<br>
