Hi Nauman,

Maybe the registrar is "fixing" the contact IP with the source IP of the REGISTER requests (which is the IP of opensips).

Can you post a SIP trace showing the request you sent to REGISTRAR and the reply received ?

Regards,
Bogdan

Hi, yes Registar receives correct contact but then changes it to the ip address 
it came from. For example Voxalot do this, its incorrect behaviour. We just 
want to know best way to workaround it.

Hi Nauman,

First you need to see who's changing the Contact hdr (from
UA IP to opensips IP) - does the REGISTER received by
REGISTRAR server carry the right Contact?

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
