Hi Oleg,

Yes the S-CSCF implementaiton of AKAv1-MD5 works with an actual SIM card for a first registration.  For Re-registration I am not 100% sure it works because it receives a previous nonce and the response is calculated over the new message, apparently there is a configuration parameter max_nonce_reuse which is relevant in this case.  Also the resynchronization I haven't tested with a real SIM card.

Best regards

alberto

Hello,
I'm wondering if ims_auth is tested with actual SIM-card/AKAv1-MD5 authentication? Bit concerned with that since as per authorize.c source code can see for AUTH_AKAV1_MD5/AUTH_AKAV2_MD5/AUTH_MD5 response is counted in the same way, though algorithms are different.
