Authenication Setup Issue
« on: August 05, 2016, 12:31:46 PM »
I am running my YATE Server in NIB mode and have input my SIM IMSIs and Kis into the subscriber.conf file (with 2G authentication, active=on).  However, the SRES that the gsm.auth code is producing is different than the SRES that I am receiving from the phone, so authentication fails.  Is there anything else I need to configure in order to have proper authentication?

We support 3 types of 2g authentication comp128 v1, comp128 v2, comp128 v3. The interface assumes that v1 is used since this is the most common. Maybe your sims use one of the other. You should check the sims specifications.

There is also a 4th type that was later added, but we don't have support for it.

To use another comp128 version you must edit subscribers.conf by hand and set op=2 or op=3 for each subscriber.
