<p>Hi, Suryaveer!</p>

<p>Are you calling <a href="http://www.opensips.org/Documentation/Script-CoreFunctions-2-2#toc15"><code>force_rport()</code></a> on the PUBLISH message? If not, OpenSIPS will send the reply to the port advertised in the <code>Via</code> header (as I can see in your trace), instead of the real port.</p>

<p>Best regards,<br>
Răzvan</p>
