<p>Actually the error is because you try to forward via UDP (proto
1). Be sure you have listen parameter for UDP and TCP sockets.</p>

<p>Hello,</p>
<p>have you look at syslog messages? Are there any
errors? Between Kamailio instances, tcp for sip should
work. Check also configs to be sure UDP is not
enforced there.</p>
<p>Cheers,<br>

<div>For some reason i couldn't register on
kamailio ims when i use only TCP protocols
between nodes, the error was solved when i
enabled UDP between I-CSCF and S-CSCF</div>
<div><br>
</div>

</div>
<div>is it mandatory for those two nodes to talk
over UDP only ? or i'm missing something ? </div>
<div>and in general for sip protocol which is
better ? UDP or TCP ?</div>
