Re: [SR-Users] Whats is wrong in this call
Hi Ssergey, the ACK seem OK, but the R-URI does not contain the "sip.instance" parameter defined in the 200 OK's Contact. Usually all contact parameter should be preserved when constructing the ACK R-URI. Does your server receive the ACK, but it is not able to forward it back to the callee (if yes, do you see any ERROR in the logs) ? Or it just don't receive the ACK at all?

Re: [SR-Users] Whats is wrong in this call
Hi, There are UAs and gateways out there which construct the ACK incorrectly and always set the domain of the RURI to the next hop. Does the Request URI of the ACK match the remote Contact in the 200 OK?
