Hi Sainath,
Created new user with "1003" and given
authentication algorithm as
"Digest-
MD5". Even i tried with authentication algorithm
as "SIP Digest" but
observed
same error as below.
Configured X-lite softfone and tried to register a user but getting error
as
"403 Forbidden - HSS Authentication Scheme
Unsupported"
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.
