What I've read about free security systems (and I've actually had a young lady peddler at the door selling this) is they scare you by mentioning recent burglaries in your neighborhood (she said this which I knew was false as I follow the police reports in the local paper), offering you a free security system, a discount if you agree to let them put up a sign visible from the road, and only at the very end will you hear about the $X/month fee for monitoring your system. Other practices I've read about are long term service contracts that they don't tell you about with huge cancellation fees (you have to essentially buy them out to get out of the contract) and sometimes the cancellation process itself is difficult and drawn out. Sometimes your "free" security system turns out not to be truly free because once you've cancelled, they begin charging a rental fee on the system (it's their system and you have it) that may be difficult to return for all kinds of stupid reasons like no return address to ship it to, etc., and they keeping charging the rental fee while you have it. I'm not saying this company is a bad company but simply warning all of you to read, read, and read through the service contract before signing.

The caller ID is Success Coffee. It starts a prerecorded spiel about something free. I hung up before the recording got to far. It seems lately there's a rash of unwanted calls and I've got a multiple line system so I get to receive calls on all lines.

The Caller ID says Success Coffee - the message is one I have heard from many different phone numbers: "If you do not want to be in Google's Business Directory press 2 now.  Press 1 to be connected, Press 2 to decline."

I received a call about IRS back taxes ! I asked who is this? They hang up!

Calls are coming to my office,  where I have multiple lines.      Calls must be generated by a computer,  because all three lines eventually start to ring at the same time,   especially when I don't answer (because from what I can see on my caller ID it is likely a "SCAM" call  - - since most of my clients are local).    So when I don't answer,  the lines continue to ring,  so that eventually all three lines are ringing at the same time.
