I'm not sure if this is a prank call or a malfunctioning phone on the caller's side. Know those voice changing machines like in the movies? Like a bad guy would change his voice, making it sound lower and mechanical. That's what the calls I've been getting sounds like, except it's either a guy prank calling with a very crappy voice changer or a guy whose phone is not working right since I can't make out what he's saying at all. This guy has been calling at least 6 times in the last 15 mins...first the home phone and then my mom's cell phone. My home phone isn't listed in the phone books and my mom only gives out her cell phones to people she knows. And after I threatened to call my phone company to get the number and report it to the police, he still calls, so I'm not so sure if this is a prank call. But the caller ID on the cell phone says the number is "861-000-0000" so I don't know what that's about. Any ideas?
