Received call, 01/13/2017, EST 11:24. Typical, no message left. I do not answer unknown calls. If it is important caller will leave a message. Another call to block.
Tried to answer call from Chula Vista CA. This is the 2nd call (diff # today from telemarketers today) I attempted to answer out of sheer curiosity no response, quick disconnect and then I called the number which did not ring at all. Very strange. I am also on the supposed Do Not Call Registry. A bit disappointed in that as it's a hassle to report each and every phone number that slips through the cracks.
This is no telemarketing call. This is a hacker. They join their number with yours and can then pretend to be you by intercepting calls. Most worrisome is when you use two step verification. Cyber crime at its worst!
