Hello,

how can i start a "Man in the middle attack", to decrypt encrypted phone calls of the DECT standard? 

I read something about it on the internet. Here, however, I lack the software and I do not know what hardware do I need to do so. The normal DECT Sniff attack I have already stated. However, one can hereby decode only unencrypted packets. Anyone have an idea?

Greetings.
