Don't answer the phone for unknown numbers. Block the number if it bothers you. When you answer the call that tells them it is a good number and they will just keep calling. Usually such calls are not from telephones, but a computer system programmed to show whatever CID they want to use. A computer is capable of calling millions of numbers randomly very rapidly and when someone answers it is logged as a good number.
For several days I've received at least four calls a day from this number starting before 11 am and ending around 9:30 pm. If I try to answer the call, the phone immediately goes to "missed call" and otherwise I just get a missed call message with no recording.
I phoned the number back. It is an automated service called "movie phone" set up by "Z100" radio in NYC. Evidently you can find what movies are showing at particular theaters and get information about them (reviews and times showing etc.) I couldn't find an option in any of the menus to turn off any sort of automated call. I wonder if it is a kind of telemarketing list issue.
I have been getting calls from this number for a few days now. My caller ID says New York Call and then the number 212-777-3456. The phone rings, but never is a message left. This morning I got a call at 8:00 AM and last night it was at approximately 8:30 PM. I am getting really tired of this!
