<p>Hello,</p>
<p><br>
</p>
<p>did the INVITE get to creating a transaction (e.g., was
t_relay()/t_newtran() used for it)?</p>
<p><br>
</p>
<p>Cheers,<br>

<p>Hi,</p>
<p><br>
</p>
<p>We tested the following on Kamailio 3.x and 4.x and
observed the same behavior.</p>
<p><br>
</p>
<p>INVITE and CANCEL are sent to Kamailo from the same source
within the same transaction. (branch value in the first via
header are the same in both INVITE and CANCEL message. Also
FROM and TO header are same as well). </p>
<p><span style="font-size: 12pt;">However, Kamailio does not
relay CANCEL message. UAC keep sending CANCEL till
timeout. Apparently, t_check_trans() returns false. </span><span
style="font-size: 12pt;"> </span><span style="font-size:
12pt;"> </span><br>
</p>
<p><br>
</p>
<p>Can anyone help me on this issue on why Kamailio does not
relay CANCEL message?</p>
<p><br>
</p>
<p>Thanks,</p>
