<p class="MsoNormal">Hi Bogdan,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Sorry, I missed your other reply. Meanwhile I advanced with my integration POC, and I’m able to exchange messages between OpenSIPS as a load balancer and Freeswitch as media service.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Where I’m stuck now is establishing a call between parties. The first invite is sent to the Freeswitch, Freeswitch picks it, tryes to establish a bridge, responds with a 100 Trying, that 100 message reach back the OpenSIPS, and nothing
else happens, I cannot see it generating a new invite for the second participant and the ringing message.<o:p></o:p></p>

<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m trying to use Freeswitch as a media server with Opensips as a load balancer, I need something very basic for a POC. (I configured the load balancer and dispatcher based on old information found here:

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m adding the X-Auth-IP header to the requests like this (this is based on the config that ships with the 3.4.x release in the docker image, so I guessed that this is where I should add the header):<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>

<p class="MsoNormal">}<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">On the freeswitch side I added the IP set by opensips in the list of allowed addresses.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Now, with or without authentication enabled on the Freeswitch side (i.e. regardless of what I set in the “auth-calls” param, or if I enable the accept-blind-auth), or even whether the Freeswitch is running or not, when I try to place a
call from/to some registerd addresses, I get the “407 Proxy authentication required” response.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Could you please give me some hints on what I might be doing wrong, or direct me to a contemporary tutorial?<o:p></o:p></p>
