<div class="WordSection1">
<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-US">I have problems with my dialog matching, using OpenSIPS 1.8.0. I have two edge proxies, A1 and A2, and an intermediate proxy B.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">An INVITE is received by A1 and passed on to B.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">B processes the request and sends in to A2.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">A2 send request to whatever destination that has been decided.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Both A1 and A2 want to keep track on state during the call so they create dialogs. So far so good.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">However, B actually load balance the requests so a request might come back to A1. A1 will then try to create a new dialog for the same INVITE. Technically speaking this is the same dialog in terms of the RFC, however
there are two dialog data structures created. I can see structures being allocated and the DID parameter in the record route header filled in properly (different values).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The problem is that the dialog matching when calling loose_route() will not find the first created dialog on subsequent requests (ACK or BYE). I am using dlg_match_mode=0 (DID only).
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Am I misusing the dialog modules when trying to create two dialogs for the same call (on ingress and egress)?
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Since I actually have got two different DID parameters on two record route headers, I cannot see why it shouldn’t work.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I cannot seem to find another way to do it, since I cannot know if I am back to the same edge proxy or not.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Regards,<o:p></o:p></span></p>
