We got a call from this number today at 11:26 am and didn't answer. The caller ID was Wellesley Hi MA. It was a robo call which left a partial message regarding rate reduction, which I assume referred to electricity. When I called back (our number is hidden by default on outgoing calls) I heard a recording which said "Hello, and thank you for calling. If you'd like to be placed on a do not call list for the number that called you, please press one now." Since our number is hidden, they must have supernatural powers which enable them to divine the number. It will be added to our call blocker.
They can't be found and taken to court because they falsify their Caller ID information and use internet phone connections to make their calls. This means it takes high technology, extensive effort, and cooperation between many law enforcement jurisdictions (often including foreign countries) to trace them. The FBI and Interpol have enough on their hands with human trafficking, terrorism and drug cartels. Annoying phone calls to you and me rightly fall quite low on their list of priorities.
I've tried to find a call blocker for a land line phone which will work with DSL, verizon Voice Mail system a fax machine, and with 2 distinct rings (3 tele number) There is no technology that will accommodate my system but caller ID works just fine. Don't know the caller ? Don't answer the phone. Also, before you spend $200 on a sophisticated call blocking machine, remember kiddies, real scam and spammers switch out numbers. you may get the same individual or company calling from 40 different phone numbers. None of them take calls and rarely is there a human beings on the other end. Yes I'm 300000 years old use one of these confounded telephone dialing machines - which works so well I can actually communicate with someone (aka hear and understand what the other person is saying) - unlike every cell phone in the world which also gives you brain cancer w/extensive use. I live close to Wellesley Hills so the caller could have been a prospective customer. But, alas, I never answer the phone and if the caller does not leave a clear concise message including contact information I guarantee this- I will not return the non-call.
