<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><br>
</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>
