Richard,<br><br>I tried calling the same number outside of Asterisk, by making direct calls from a landline telephone and a mobile phones. When the user rejected the call, the call was immediately cancelled.<br><br>This implies that for whatever reason, the call reject signal is not available for asterisk to process, even though the network processes the event.<br>
<br>We use a digium TE420 card(<a href="http://www.digium.com/en/products/digital/te420.php">http://www.digium.com/en/products/digital/te420.php</a>) to connect to the PRI. To debug the scenario, how do I do the following:<br>
a. Is there an ISDN signal for call reject/denied?<br> I'm sure there is, for reasons explained above.<br>b. Is my service provider passing along the call reject/denied signal to the PRI?<br>c. If the signal is passed along to the PRI, why is the card not recognising the signal?<br>
<br>Call Reject is a pretty common feature and is in common use everywhere. There must be a simple way to fix this.<br><br>--<br>Thanks,<br>Ishwar.<br><br><div class="gmail_quote">On Mon, Aug 1, 2011 at 7:36 PM, Richard Mudgett <span dir="ltr"><<a href="mailto:rmudgett@digium.com">rmudgett@digium.com</a>></span> wrote:<br>

</div>As far as the ISDN signaling is concerned, the call is still going.<br>
There is no signaling to indicate the call is not going to proceed<br>
any further.<br>
