Called my cell, I didn't answer. Came through as a company called Coresite out of Los Angeles. Called it back and of course it's a non working number. http://www.coresite.com/
Got a call from this # -- I answered it - it was a recorded message stating that they are a security company working with local Police Departments and FBI!!! They wantted to install some type of security system in my backyard??! they said to stay on the line to speak with a 'representative' - I hung up. Looked them up on google found that same website- made no sense- I actually called them back a day later from a different phone and the recording said that ' you have reached a 'coresite non-working number'. Sounds like a big SCAM to me---
