<p>Hello,</p>
<p>that is the received CANCEL, not the one sent out by Kamailio.
The Via branch generated by Kamailio has the format present in the
CANCEL sent to downstream.</p>
<p>Probably there is some setting in the system (ip forwarding)
causing it or something else out of Kamailio control.</p>
<p>Cheers,<br>
Daniel<br>

<div>Got this weird "problem", where CANCEL request is relayed
to both the right destination as well as the 255.255.255.255
broadcast address!? I have no such logic in my script, that's
for sure.</div>

<div>I doesn't do anything harmful (as far as I can tell), but
I'm just curious why it's doing that. Any ideas?</div>
