<tt>Hi Nabeel,<br>
<br>
Using TCP gives an advantage over UDP as being connection
oriented, it force the NAT pinhole to stay open. Nevertheless,
using the SIP pinging with UDP should also have fixed the problem.<br>
<br>
I will update the default cfg to use SIP pinging rather than
simple UDP pinging.<br>
<br>
Thanks and Regards,<br>

that not right? I'm fact, using a TURN server

I suppose you OpenSIPS seats on a public
IP, right ? The callee looks to have a
private IP. And, at IP level, it is
impossible to route from a public IP to a
private one.<br>
<br>
I see your script has NAT traversal
support. My question is - did the callee
properly registered via this script ? can
you do an "opensipsctl ul show" to see the
callee's registration ?<br>
