Hello,<br>
<br>
send the ngrep trace of such call, from the initial INVITE, you can
use:<br>
<br>
ngrep -d any -qt -W byline port 5060<br>
<br>
The sip trace will help to see what is wrong with that CANCEL.<br>
<br>
Cheers,<br>
Daniel<br>

<div>Problem: </div>
<div>When call is initiated from a softphone and is in ringing
phase, CANCEL just don't work. I've done some initial
debugging and the following piece of code in main route is
failing.</div>
<div><br>

<div><font face="'courier new', monospace">if
(is_method("CANCEL"))</font></div>

<div><font face="'courier new', monospace"> }</font></div>

<div><span style="font-family:'courier new',monospace">
exit;</span></div>
<div><font face="'courier new', monospace">}</font></div>
</div>
<div><br>
</div>
<div>Also the CANCEL fails the has_totag() condition !</div>
<div><br>
</div>
<div>The same Call CANCEL scenario works fine for any client
on Public IP !</div>
<div><br>
</div>
<div>Hope to get some pointers for the solution.</div>
<div><br>
</div>
<div>Regards,</div>
