Got a call from this number, it was a Robo-Automated Home Security Scam caller, selling home security systems.
Called the number back and it was the "fast" beeping Busy tone, usually indicates a disconnected line.
If it was an operative line that was in use, it is usually a slower intervals of the busy tune.
Anyways, it looks as if this is a "Generic" number that Scam Artists and Collection Agencies use to "Hide" (via Number Spoofing) their real number they are calling from.
This company / phone number has called me continuously just about every other day trying to sell me a security system and I have repeatedly pressed #2 to be removed from their list. today I pressed one and wanted to know their toll free number and she asked why and I said in case I need to contact you about my security system once it has been installed and she said they didn't have one and then hung up. I have a 4 line predictive dialer and when a company calls me repeatedly and tries top sell me something in spite of my being on the National do not call registry. They seem to think its okay just to keep calling because they claim the government wont prosecute them. Well I tell them that every time they call me I'm going to call their toll free number 1000 times and that will end up costing them a hundred dollars every time they call me. the few times I have actually done this I will get a call begging me to stop calling them and I explain that my time is money too and if they call me again it will be 2000 times they haven't called back.
