Hi Bogdan
Yes, UAS is an opensips too, by chance.

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.
