Dear List

I am observing a strange behavior on gsm network.

I have my own gsm impersonating tool. I also have S2 with logging enabled
on wireshark.

I take TMSI of S2 simcard and put it in impersonating tool. and place call

It ask me authentication but when i place call with S2 it doesnt ask

why its asking authentication while impersonating but not while using S2

note: S2 is registered on network with proper sim card.
