SuchCalls Brings Encrypted Phreak Fun to Smartphone Calling – Motherboard.

Here, there, everywhere a new encryption app. Now there’s SuchCalls, a project helmed by hacker and privacy advocates Jered Morgan and Teli Tuketu that brings the underground art of phone phreaking to the masses in a (somewhat paradoxically) encrypted fashion. Not only are there easter eggs planted via various numeral combinations, but users can pay for calls in Dogecoin. SuchCalls also offers blocked caller ID unmasking, in-call recording, and phreaker “bridges”—conference lines for anonymous, encrypted conversation.
