Hi,
I have modified the Xlite configuration. Now user is failed to REGISTER
with
"401 unauthorized - challenging the UE" to challenge the user, here user
is
not sending any response with authorized details.
Xlite client does not use the IMS-AKA based authentication but SIP digest. Therefore you must adapt the authentication for the user (bob) in HSS accordingly and set in the default authentication algorithm in the parameter-file scscf.cfg to "HSS-selected" (define REG_AUTH_DEFAULT_ALG "HSS-Selected").
