When you're prank calling using a voip service, and a store manager or anyone for that matter, threatens to trace the telephone call, can they really identify where the call originated and who made it? I know that government agencies have their hands all over skype, but as far as others, can your identity be discovered? This is hypothetical of course. Do shady, foreign voip providers keep records of calls and their IP addresses? Would law enforcement stateside have any ability to obtain these records? I'm just curious, aha. I'd appreciate any feedback and please refrain from flaming me.
