Subject: Re: [OpenSIPS-Users] ACK did not Receive on Proxy
and get in loop<br>
<br>
Hi Hamid,<br>
<br>
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 ?<br>
<br>

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. </div>
