Subject: [Sip-implementors] Regarding bad Authorization header params
inRegister msg

Hi,
     When REGISTER  msg  sent from UAC with   Authorization  header 
with  invalid  params i.e nonce, then what response code has to return
from UAS?.

Basically the decoding the non-mandatory headers parsing failed in sip
stack. So in that case how UAS has to behave?  Is it needs to send 400
 bad request  or drop the msg i.e no response to UAC.

[ABN] I think the message must be processed normally as it's an optional
header. If the nonce parameter is missing or authorization header
missing it should have challenged with 401 responses.

Thanks&Regards
kesav
