I recieved a call with no one on the other end of the live twice. Once the call went to the answering maching where nothing was recorded and the other I answered and no one was on the other end.
This is RI number from a company called PC Call - you make the call through their directory to whom ever you are calling. If I called anyone on the planet through PCCall 401-424-9005 would show at the receiving end. No worries it is a cheap way for people to call long distance throughout the world. I know because I use it
