This seems to be a shell to hack you DNCL or to block important calls that would enable business development. 860 269 3408. Called my voip , vonage,company line with a block this call message 1 or 2. I called from other lines, Verizon, and it is a non working number. From voip it answers same recorded message I believe this is an ATT switched number. 3 bucks per month .anyone can buy them.
