GSM Voice Decryption From Start To Finish (2G Non-Hopping Only)

The GSM data used in the making of this video was recorded and decrypted with unanimous consent from the owner(s) for the purpose of demonstrating the 2G decoding features of gr-gsm and for evaluating cellular network security.

Due to it's complexity and difficulty, decoding 2G phone calls is considered by most to be the hardest task to accomplish in the realm of GSM decoding. Differing voice codecs, varying channel data rates, arbitrary allocation of frequency hopping and carrier-specific network configurations add too many variables into the mix to make it a straight-forward enough goal to achieve.

I showcase the entire 2G voice decryption process from start to finish, excluding the actual recording of the GSM data
