The telephone number was a duplicate of mine except for the last 4 numbers. For this reason, I just picked up and said nothing. However, the line was already dead. When I hit the end call button there was no change. Some info. from the Detailed Information Window: Here is the OPERATOR: Билайн. The window showed 18 views. A red rectangle in the upper right corner says It's A Mistake. Will add one other thing. My number is a Google Voice Number.
