Please, as a general guideline: anytime you are facing problems attach logs and
configuration files of all components.

Hi,
Till now I have always worked with simcards without knowing their ki so I was not using
any encryption. I have recently bought some programmable simcards and gave them an IMSI
and KI and tried to have them working with ‘encryption a5 1’ and ‘encryption a5 3’ and I
faced some problems. First if I choose 'a5 3' the phone cannot connect to the BTS
and nothing can be done, while if I set the encryption to 'a5 1’, the phone connects
normally and can make and receive calls but sometimes the call fails for a reason that I
don’t know. I have then tried the following setup:
I have connected 3 phones A, B and C. A and B have no KI related to them so no encryption
is applied while C was given a KI.
If I call from A to B or from B to A, the call is done successfully every time, while if
I call from either A or B to C or from C to A or B the call might work and might not. Is
there something in the configuration that should be changed when adding the encryption
support ? And how to enable the a5 3 encryption ?
Best regards,
