[SR-Users] Re: Contact does not exist in PCSCF usrloc error in log

Hi Supreeth, I made necessary changes in the sipp side to put the domain name instead of the IP of the xcscf. Now the SIP registration progresses to the point where the xcscf is challenging sipp with 401 Unauthorized and sipp is responding back with the authentication credentials (e.g for the 1st UE -> [authentication username=001010123456791 aka_OP=0x11111111111111111111111111111111 aka_K=0x8baf473f2f8fd09487cccbd7097c6862 aka_AMF=0x8000];) I took the OP, K and AMF values as programmed in the FHoSS. I am enclosing the pcap and syslog snips for the transaction. Please let me know if any more information is required.
