What is the difference between a SIP 401 Unauthorized and SIP 407 Proxy Authentication Required?
I assumed SIP 401 is for REGISTER messages and SIP 407 was for INVITE message challenging Am i correct? Thanks Harshith _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
