Hi guys..
I have a question about cipher mode. I saw, that currently a5/1 and a5/2 is implemented. Now, I want to force the phone to use no encryption (A5/0). Is it enough to disable both of these algos?
Because when I tried that, I was not longer able to sign in..
Are there any patches that are necessary, or may it be, that the network is not willing to provide a non-encrypted connection?
Usually, the phone is using A5/1 and with that algo, everything is working fine..
Thanks for your help.
Ronny

The network will indeed most likely refuse you as you found out.
Nothing you can do about it, the network is the master and since the specification says a phone _must_ support A5/1, the network is totally in its right.

I didn't know that A5/1 is a must nowadays..
Thanks for the competent information ;) Then I have to search for othr ways ..
Thanks, Ronny

It's always been a must for the MS to support it. The network doesn't have to, but the phone does.

Have your own BTS (like nanoBTS, or openBTS, see http://www.ebay.com/itm/220863984566 ) or BTS simulator (like a racal 6103e)
