[SIPForum-discussion] Authentication-Info header

[Sonja Belic]

Hi all,
I have a question regarding Authentication-Info header field. If we send 
INVITE message and receive 401 or 407 with, for example, three different 
challenges ( three Authentication header fields ). So, we re-send INVITE 
with three credentials ( three Authorization header fields ). When we 
receive 200 OK for that INVITE, it can carry one ( or maybe more ) 
Authentication-Info header fields. As I saw, only mandatory parameter in 
this header is "nextnonce" value. So, haw can UAC know for which of 
these three credentials to set this "nextnonce" value?

Thanks in advanced.
Sonja
