Betamax and the VOIP triplets

So Skype is the reigning king of the VOIP but what viable alternatives are there at hand? German company Betamax offers three different versions of the same application: VOIP Stunt, VoipBuster, and VoipCheap. The difference between the three? Not much, to tell the truth, apart from the interface. They all offer the same rates, simple features and a promotion for free PC to phone calls when you sign up (and buy 10 Euros of credit). What really makes one stand out from the others is the different countries to which you can make free calls. Choose wisely and you’ll be able to chat endlessly for free!
