Thank you for your response, Luca.

I measured the timeout in one base station of each provider in
Austria. The timer is set to 12s in all cases.

In addition, all measured base stations allow the use of A5/0, if the
MS doesn't indicate support for A5/1 and A5/2.
This even contradicts the GSM specifications (TS 43.020):
"The network shall not provide service to an MS which indicates that
it does not support the ciphering algorithm A5/1."
