<tt>Hi Tito,<br>
<br>
Note that the tcp_connect_timeout is in milliseconds, so maybe 3
ms is too short for getting back the SYN ACK.<br>
<br>
The logs are keep reporting the failed connect. You say the
connect is ok, the INVITE is sent forward to callee and there is
also an 180 response? ....and then you get the 500 reply ?<br>
<br>
Regards,<br>

Well, from OpenSIPS perceptive it is a "Connection
refused", so the destination is rejecting the connect.<br>
