Jea, tnx, I know that in our country having a TEA1... But some terminal working on clear mode, so this I'm not understanding why they working on clear, but osmocom show me that we have a air encryption 1...

Thanks.

It could be any of the TEA algorithm. I don't think which algorithm is used is broadcasted, in theory each radio only supports one of the 4 algo ... so it's assumed you bought the right radio option :p
So that's it? If is encryption 1, i can't use speech decoder for voice, right?
Nope.
Cheers,
