Hi,<br><br>I have two SIP servers, <b>A</b> and <b>B</b>, connected each other though a OPENVPN tunnel. The server <b>B</b> needs to t_relay() every SIP message containing the method MESSAGE to the server <b>A</b> but these messages never reach destination. <br>
<br>I have tested the tunnel connectivity and works fine. I wrote a Perl script (located in <b>B</b>) that sends SIP MESSAGES to Kamailio (located in <b>A</b>) trying to figure out what is happening but these messages are received by <b>A</b> and processed correctly but when <b>B</b> does the same from Kamailio, it is never received.<br>
<br>Here is the route part of kamailio.cfg in <b>B</b>:<br><br>Observation: ($rU == "1004") result is <b>true</b><br><i><br> if(is_method("MESSAGE"))<br> { <br> if($rU == "1004") <br>
{<br> xlog("L_INFO","En 1004");<br><br> rewritehost("10.8.0.1");<br><br> if (!t_relay())<br> xlog("L_INFO","MIO Error en t_relay");<br>
<br> t_reply("200", "Ok");<br> xlog("L_INFO","MIO despues rewrite");<br> exit;<br> }<br>
.....</i> <br><br>The perl script that WORKS:<br><br><i>$msg = 'MESSAGE <a href="http://sip:1004@192.168.1.2:5060">sip:1004@192.168.1.2:5060</a> SIP/2.0<br>Via: SIP/2.0/UDP 192.168.1.2<br>From: "2002" <<a href="mailto:sip%3A2002@192.168.1.2">sip:2002@192.168.1.2</a>>;tag=1837944796<br>
