I rec'd a call from this number on my cell phone yesterday during lunch.  Since I didn't recognize it, I let it go to voice mail, but no message was left.  

I called from another phone inside our company's pbx system and received a recorded message saying if I wanted to be removed from their call list, press 1.  I didn't press any keys and after a few seconds of silence, was disconnected.  No mention of what type of business they were, or products they offered.  Where did the reference to an alarm company come from?
