It is USA Alarm out of Dallas Tx. 214-974-0665

Got a call from this number with Caller ID of "AMERICAN GUARD" but they left no message.

Same thing - probably a scam call.

Got a call from this number @ 9:35am 21 mar 14. I don't answer unknown numbers and all friends and family know that
to leave a message or I might pick up. Screw these robo callers, We need to have a death penalty for robo callers and
I'm talking about the person who is the root of this problem. Maybe a healthy fine of the phone company's for allowing
this scum to use their phone system might stop this!

Caller ID said "USA Alarm" - let's see - how stupid would a no-call lister have to be to entertain any unsolicited discussion from a stranger regarding their home security system? Speaking of security, with the mere push of a button - problem solved, added to my call blocker! Thanks for calling, moron!
