I am in Connecticut and just got a call from this number. I do not answer if I do not recognize the caller-ID, then if they do not leave a message I assume they are a telemarketer and I block the number. So this number has been added to my blocked call list.
My phone number has been on the National Do Not Call Registry since August 2003 so if they are telemarketers, they are violating the law.
To block calls like this I got a Panasonic KX-TGE245B that allows me to block up to 250 numbers and/or area-codes. Panasonic has several new 2014 models that will block that many numbers. You simply save the CID to the blocked list. You can also block area codes by adding them to what they call a “Range List” (you are blocking the range of numbers starting with that area code).
There are several types of call blockers & call blocking phones. I suggest you get one so at least you only need to deal with any caller once.
This was from Liberty electric Co. (I think that's what she said.). The person asked to speak to the person who makes the electrical supplier decisions. So they want to sell electricity. She said they were authorized to sell electricity in CT. There was no Compant name on the CID. I told her I already have a supplier. She asked who that was and I told her. Call was over.
