Who called from 7177417000

this number shows up on caller I.D.
All you hear are beeps like waiting for a fax to answer

This number has been driving us crazy too- A couple times a month it starts, and it will keep calling back every 5-10 minutes.  It only beeps, and calling back gets the "number no longer in service" message"  A real PITA!

I have the sam eproblem, it happens every couple of months.  
Same as Al above, you can't call back and the calls will continue for hours.

Calls repeatedly for a few hours, every month or so. Never answers, only beeps.
