OK, imho: obviously, the call setup succeeded after beeing challenged by your x-cscf - this means, the challenge in the 407 - Response was interpreted correctly and used for the 2nd INVITE-request by the sipp uac. The x-cscf accepted the credentials and forwards the INVITE-request to the sipp-uas. So, from cscf-side, there is no reason to send a 407 to the second invite request.
So, there might be two explanations: either, you have a completely non-3261 conform core, which does something completely wrong, or the 407ers are retransmissions of the first one according to the 1st INVITE. How to find this out? Well, the retransmitted 407 are absolutely identical to the the first 407 and arrive 0.5, 1.5, 3.5 and 7.5 seconds after the first 407, br Michael mwilliam prusty schrieb: > Hi Michael > > My S-cscf is configured in such a way that , until it gets the > credentials for the INVITE request , it will not pass the INVITE request > to other endpoint, Here After getting the Second INVITE(cseq=2)with > authorizatoion, header field, it is forwarding that INVITTE request to > other end point.
