[SR-Users] How to enforce REGISTER with AKAv1 (IMS)

[Moshe A]

Hello,

How can we enforce REGISTER with AKAv1?

Here our setup

1. kamailio version 4.3.4 for IMS
2. Boghe IMS client v1.0.58.550
3. scscf.cfg is configure with:
#!define REG_AUTH_DEFAULT_ALG "AKAv1-MD5"
4. Set Authentication Schemes in Private User Identity - IMPI for user bob
to:
Digest-AKAv1 (3GPP)

results:
First REGISTER fails with 401 Unauthorized
Second REGISTER 200 OK, but the REGISTER is MD5 and not AKAv1


Attached is tcpdump.

By the way: in which DB should we find Authentication Schemes? can't find
it in hss_db, kamailio and not in scscf.

Thank you,
Moshe.
