<p class="MsoNormal">Hello Everyone!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Hope you’re all doing well.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I seem to be having an issue.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Basically I’m using OpenSIPS as a proxy that will receive request from UAC’s, then query a database to find out what Sipserver it belongs to then store the result with cachdb_local as an $avp variable, and finally modify the R-uri of the
sip message to the UAC gets to the correct endpoint. I’ve got it working for the most part however I seem to be having an issue when I try to have multiple UAC’s hit the proxy.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I think whats happening is the value stored in memchache is the first Sipserver the proxy gets a request for.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For example:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If UAC1 sends a REGISTER to the proxy and the proxy finds out it belongs on SIPServ1 it then sets the AVP to sipserv1<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Now a few minutes later UAC2 comes along with a same REGISTER request but this time it belongs to SIPServ2, however this time it receives a 403 bad auth from sipserv2.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here’s my current logic for DB query and memcache store:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">NOTE: This is also in the REQUEST Route section of my logic, so this takes place before it hits any other routing logic.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">if(cache_fetch("local","PBX",$avp(PBX)))<o:p></o:p></p>
<p class="MsoNormal"> {<o:p></o:p></p>
<p class="MsoNormal"> $rd = $avp(PBX);<o:p></o:p></p>
<p class="MsoNormal"> xlog("this is the value of the modified R-uri: $ru\n");<o:p></o:p></p>
<p class="MsoNormal"> }<o:p></o:p></p>
<p class="MsoNormal"> else {<o:p></o:p></p>
<p class="MsoNormal"> avp_db_query("select Servers.ipaddress from Servers where Servers.ID in (select phone.ServerID from phone where phone.mac in (select MAC FROM `phone_registrations` where auth_userid = '$fU'))", "$avp(PBX)");<o:p></o:p></p>
<p class="MsoNormal"> cache_store("local","PBX","$avp(PBX)",1200);<o:p></o:p></p>
