VoIP Service Provider Lists
With all of theservice 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. Plus, there are all kinds of new alternatives in the market now to traditional carriers that enable one to use a mobile phone and still take advantage of low calling rates.
So what we have decided to do is compile a list of web sites that serve primarily to list VoIP service providers and new, cool calling alternatives.
