Hello,<br>
<br>
I will look over it soon - since you sent pcap I couldn't look at it
directly from the email. ngrep outputs plain text which is easy to
read from email, the reason I am asking mainly for ngrep traces
since many times I am not around a computer where is convenient to
open pcap file. On the other hand, if it is a transmission problem
(at transport layer), pcap file is better.<br>
<br>
Cheers,<br>
Daniel<br>

<div>This is a setup with Kamailio in front of Asterisk Servers.
Kamailio is multihomed and MS are on private IPs, all the calls
are routed to MSs and then comeback for further dial-outs.</div>

<div bgcolor="#FFFFFF" text="#000000"> 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>

</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>
