it's called IP Relay calls. They have operators who read exactly what you type to the person you call. They get paid per minute so they usually go along with it except for some who tell the companies but I'm not sure what they can do to you. The system was made so that deaf people could call people from their computers. Lots of people just learned about the system and are abusing it for prank calls. The number that called you was probably from an IP Relay service but it was probably one of your friends prank calling you.
