VoIP Service Provider Lists

With all of the VoIP service providers popping up all over the world these days, we gave up on trying to compile a complete list of all of those companies ourselves—there are just too many! By some estimates, there are more than 2000 companies that can rightfully claim to be VoIP service providers.

What we have decided to do, instead, is compile a list of web sites that serve primarily to list VoIP service providers.
