Hi Hamid,
I see the UAS is breaking the contact by re-writing it with the IP of
the proxy. Is the UAS an opensips too, by chance ?

I used local cache to store the Request URI and then changed the
contact Header of 200 OK at Proxy by replacing the contact from RURI.
It worked for me. But you can see in 200 OK UAS-Proxy that UAS is
changing the Contact with proxy IP.
