Please look into the tracefile. The Diameter MAR in packet#18 contains
AVP: SIP-Authentication-Scheme(608) l=28 f=VM- vnd=TGPP
val=Digest-AKAv1-MD5
which leads to " HSS Authentication Scheme Unsupported", because HSS now
expects to challenge with Digest-MD5.
That means that the S-CSCF still uses "AKAv1-MD5" as default authentication
schema.
You should change/enable REG_AUTH_DEFAULT_ALG "MD5" in scscf.cfg or - as a
better alternative - use "HSS-Selected".
Then try again.
