Meh it worked for me. Was explained to me as: You'll get put on a list of dead numbers. Most of the scammers use autocallers so speaking into the microphone is what triggers the connection, so you answer but when no noise ever goes into the microphone (cause mute) the auto caller hangs up. It never registers a person on the other end and sorts you onto the list of dead numbers.

You should just trust me, I've been on the run from the CRA and CBSA for years with hundreds of warrants out for my arrest but they lost track of me when I did this.
