<p class="MsoNormal"><span style="font-size:14.0pt;font-family:"Cambria","serif";color:#1F497D">Thanks Daniel. I got it basically working with the following config. But there is one last bug. If client B connected and registered, then disconnected without
proper unregister, it seems the location table didn’t get prompt update. If client A sends Invite right after that, the sip server will try to connect to B(which will surely fail since B is behind the firewall), instead of sending 480 to A right away. Is
there a way to fix this?<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:14.0pt;font-family:"Cambria","serif"">Both A and B make tcp connection to ser proxy server. If A sends “Invite” to B, ser would look up the tcp connection of B, and relay the sip request. If B is not connected,
then 480 is returned to A. When B sends back the response, ser would relay it to A.

<p class="MsoNormal"><span style="font-size:14.0pt;font-family:"Cambria","serif"">It looks really simple, but I just can’t figure out how to do it.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:14.0pt;font-family:"Cambria","serif"">what default config file you started with?<br>
<br>
Apart of that when the user is not online, the default config replies with 404 Not Found, the relaying between phones when they are online is done there, being a combination of calling function from registrar and tm modules. So, if you start with the default
config, no matter is Kamailio or SER flavour, routing of the calls between online users is provided there, just go through it in order to understand better.<br>
