Hi, I have a scenario here in the lab. I was wondering if I could ask couple of questions.
MTA P-CSCF Register (Empty nonce) ------------------------> <----------------------------------------401 (with nonce) Register (nonce)------------------------------------> <-----------------------------------------200OK INVITE (nonce)------------------------------------> <---------------------------------------407 (new nonce) ACK-------------------------------------> INVITE (new nonce) ----------------------------------> <--------------------------------------100trying <---------------------------------------180ringing <----------------------------------------200OK ACK------------------------------------> Register renewal (Empty nonce)-----------------------> <--------------------------------------401 (with nonce) Register (same call-id as previous register, nonce)--------------------------------> <----------------------------------------200OK Call is dropped. Couple of questions: 1) Should the Register renewal have the empty nonce. I think it should have the same nonce as the INVITE. 2) Should the call be dropped after 401 for the registration renewal? I am thinking since the Register renewal did eventually got the 200OK, may be MTA should have kept the call alive. I'd appreciate your responses. Thanks, Vivek. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
