[OpenSIPS-Users] Fw: Using same DNS resolved ip

[Nauman Sulaiman]

Just to clarify, i have the following setup

UA ---- Opensips ------- Callcentric Voip Provider(for example)


I wish to have the UA register with Callcentric via Opensips as outbound proxy so that all future invites come via it. I have not being able to get any UA ( Bria etc) to register with CallCentric which leads me to think there is a problem with my script. Registering with providers who do not do load balancing is straight forward. It's just with providers such as Callcentric, what happens is as i am just using Opensips as a relay for registration the 407  from Callcentric is passed back to the UA which sends another REGISTER request, this is then sent to a different IP (different callcentric proxy) by Opensips, presumably because it does a fresh look up.

here is my script which deals with register requests:

 if (!uri==myself)
        {
               
                route(1);
        }



In route[1] 

 if (method=="REGISTER")
 {
      if (!t_relay()) {
                sl_reply_error();
                }
     exit;  

 }

This works with most providers but not those doing load balancing.

Thanks
