Yes, we know this. But DSD doesn't decode encrypted audio so how does that help?

You have to modify it, all voice frames are xor'd with the BP key hence its very simple.

..... Because modifying someone else's software is so easy to do.

A real alternative would be an ACDR25 board if one could be found. It'll decode BP and I believe it ignores RAS errors.

More falsehoods. If a BP key of 1 is used, the AMBE frames are not xored with '1' or '00000001' or any other form of 1. Instead, the actual xor pattern has far more of the bits set. So why are you deliberately lying?

Wow, accusing me of lying now, what a nice person you are, NOT.

If you don't have a clue then maybe you should shut up!

Who said the BP key was 1, each of the 255 keys is 49 bits long, how on earth could you think a key could be 1, if you don't understand just don't bother posting.

Thread closed. Respectful discussion is always welcome but it looks as though this thread has turned nasty.
