It's a company called Comedy Calls. People pay them $1, $4, or more to place prank calls to their friends for 8 cents each call. The person above is getting these prank calls from someone that knows their number. The pranks range from Silly to Naughty R-rated calls and there are 3 options for the caller ID; Your own number, Comedy Calls number, or reverse ID which is the same number that is being pranked. If the number on the Caller ID is not the 828 or your own number, then it's the pranksters own number and this is what you look for. Since it's a pay site, the calls shouldn't persist for very long.
I got the call too. They did not leave a message. I called the number. It was a prank call. Block that number if you can do it. I download Mr. Number on my cell phone to have the number blocked.
