[OpenSIPS-Users] Opensips outbound proxy problem

[Nauman Sulaiman]

Hi, we are using opensips as outbound proxy. We have a problem when a UA
registers with certain servers via opensips but the contact address returned by the registrar is that of opensips rather than the UA. Both the UA and opensips are on public ip and we have opensips inserting path header. Just some registrars behave incorrectly.

UA ---------> Opensips ------------> REGISTRAR

Are there any standard tricks/techniques we can use in opensips to route any INVITES/ACK/BYE back to the UA as the RURI are set to the opensips proxy address rather than the UA. 

Thanks
