Re: [OpenSIPS-Users] ACK did not Receive on Proxy and get in loop

In that case, you probably do a wrong fix_nated_contact() or similar forthe 200 OK reply coming from a not-nated entity.

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 ofthe 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.
