<div dir="ltr"><div>Hi All,<br></div><div><br></div><div>Hopefully a simple question related to the behaviour of the presence module on my registrar. </div><div><br></div><div>I have configured OpenSIPs to enable dialoginfo updates against specific user agents. When the user agent places/receives a call the PUBLISH event is generated correctly. This resolves a UA at a locally served domain and pushes the request out to the public address of the local server. In my environment this server is behind NAT and we end up seeing requests being generated and sent from the internal interface to the public address of the sending server which seems wrong, at at least inefficient. </div><div><br></div><div>Is anyone able to suggest an improvement to my configuration, perhaps I can improve domain awareness somehow? Is this the correct behaviour?</div><div><br></div><div>Many thanks,</div><div><br></div><div>Callum</div><div><br></div><div>----</div><div><br></div><div>Relevant configuration (running OpenSIPs 3.0.1):</div><div><br></div><div><font face="monospace">loadmodule "presence.so"<br></font></div><font face="monospace">loadmodule "presence_dialoginfo.so"<br>loadmodule "pua.so"<br>loadmodule "pua_dialoginfo.so"<br><br>modparam("presence", "server_address", "sip:<i>public-ip</i>:5060")<br>modparam("presence", "mix_dialog_presence", 1)<br>modparam("presence", "fallback2db", 1)<br>modparam("presence", "max_expires_subscribe", 14700)<br>modparam("presence", "max_expires_publish", 14700)<br></font><div><font face="monospace"><br></font></div><div><font face="monospace">...</font></div><div><font face="monospace"><br></font></div><div><font face="monospace"># Fired when placing a call</font></div><div><font face="monospace">route[ENABLE_BLF_CALLER] {<br> xlog("L_INFO", "INFO: Enabling presence for calling party ($fu) ID:$ci\n");<br> dialoginfo_set("A");<br>}<br><br># Fired when receiving a call<br>route[ENABLE_BLF_CALLEE] {<br> xlog("L_INFO", "INFO: Enabling presence for called party ($ru) ID:$ci\n");<br> dialoginfo_set("B");<br>}</font></div><div><font face="monospace"><br></font></div><div><font face="monospace">---</font></div><div><font face="monospace"><br></font></div><div><font face="monospace">Example transmission:</font></div><div><font face="monospace"><br></font></div><div><a href="http://192.168.153.210:5060">192.168.153.210:5060</a> -> PUBLIC-IP(of <a href="http://example.com">example.com</a>):5060<br><br>PUBLISH <a href="mailto:sip%3A12345@example.com">sip:12345@example.com</a> SIP/2.0<br>Via: SIP/2.0/UDP 192.168.153.210:5060;branch=z9hG4bK4316.2ff8a84.0<br>To: <a href="mailto:sip%3A12345@example.com">sip:12345@example.com</a><br>From: <<a href="mailto:sip%3A12345@example.com">sip:12345@example.com</a>>;tag=260776ec80eaeff43e316f7930643583-5872<br>CSeq: 10 PUBLISH<br>Call-ID: <a href="mailto:0168d45862da3b23-189847@192.168.153.210">0168d45862da3b23-189847@192.168.153.210</a><br>Max-Forwards: 70<br>Content-Length: 643<br>User-Agent: me<br>Event: dialog<br>Expires: 301<br>Content-Type: application/dialog-info+xml<br><br><?xml version="1.0"?><br><dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" state="partial" entity="<a href="mailto:sip%3A12345@example.com">sip:12345@example.com</a>"><dialog id="1ca15ca3-215b-4d9d-b401-770408889a6a_I_3150144_A0_5da442c9a33f9.0" call-id="1ca15ca3-215b-4d9d-b401-770408889a<br>_I_3150144_A0_5da442c9a33f9" local-tag="1323791516" remote-tag="UvKaaK3vUvega" direction="recipient"><state>early</state><remote><identity><a href="mailto:sip%3A01728726500@192.168.153.226">sip:01728726500@192.168.153.226</a></identity><target uri="<a href="mailto:sip%3A01728726500@192.168.153.226">sip:01728726500@192.168.153.226</a>"/></remote><<br>cal><identity><a href="mailto:sip%3A12345@example.com">sip:12345@example.com</a></identity><target uri="<a href="mailto:sip%3A12345@example.com">sip:12345@example.com</a>"/></local></dialog></dialog-info><br><br></div></div>
