[SR-Users] ims_auth with AKAv1-MD5

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
