In my opinion, there's no way that this is an actual intelligence or military operated switch.

I'm not firm in this belief because of the open nature of a phone line like this (that part seems fine), but because there is no reason for a real switch to use actual terminology like "agent" and "compromised."

This reminds me a lot of a Capture the Flag contest: you know you're not really hacking an intelligence agency, but sometimes it's fun to pretend.
