Called my cell number about an hour ago, it left a VM. The canned message started talking before my phone's announcement finished, but what I could make out was a sales pitch for another home security system. I already have one, it uses .45ACP and works whether the power has gone out or not.
Now if they were selling a phone security system that traces back to these illegal tele-scammers on the other end and zaps their head with, say, 200,000 volts at about 1000 amps, I'd buy one in a heartbeat.
