I've gotten multiple calls from this number for about 3-4 weeks.  I hope they stop calling because it's getting really annoying.  "A Security" is what shows on the Caller ID.

I have too and i have been wondering who this caller is.

I finally broke down and answered and they said I was pre-selected to receive a 'free wireless' alarm system if I allow them to place one of their small signs in my yard for 'advertising'. When they asked if I owned the home, I said no and then they wanted to know what current security system I was using.   I thanked them for the offer but was not interested before hanging up.
