Called, left no message.

Automatic voice offering to install free security system in my home.  Caller ID says  from Somerville, MA.

Recorded robocall from "Peter" Claimed that home burglars cut landlines so you can't call 911 if they get caught in the act. Said that they offer a wireless pendant that with the push of a button will have fire police and EMS at your door in 18 seconds, the fastest response time in the USA. I happen to be interested in pursuing a career in that industry, so I know that is physically impossible. If you get this call, alert your local authorities, as it is a scam.

We got a call from this number today at 6:21 pm. The caller ID was "SRVC CALL". We did not answer and no voicemail message was left. When I called back I heard a recording of a male voice which said "Sorry you missed our call. If you received this call by accident and would like to be placed on the do not call list please press one now." The recording repeated until I hung up. Our caller ID is blocked, so this couldn't work. I called again and pressed one just as a test, and nothing happened except that the recording stopped repeating and hung up.

Called here and hung up on me.
