Over the past five years it has become increasingly difficult to keep an overview of all the worldwide operating VoIP services or Broadband phone providers. New VoIP / Broadband phone VoIP services are launching almost on a weekly basis and it has become almost impossible to compare PC to Phone and Broadband Phone service providers without weeks and weeks of time consuming research. Each VoIP provider proclaims to have the best service and the cheapest local, long distance or international VoIP phone rates, but the differences are still substantial (up to 1000%), although in most cases the VoIP services are cheaper than most traditional telephone companies (PSTN). Choosing the right Voice over IP service for your specific need and calling pattern, especially if you make regular international calls can save you a small fortune every month.

Over the past two years a new group of VoIP service providers have been making their mark in the VoIP market. These providers are offering free VoIP calls to a wide range of destinations and are capturing a significant market share. Being the first VoIP service to offer these free calls, VoIP Buster is the best known, but every few months sister companies are launched to keep the momentum up, but all offer basically the same services. Some of the sister companies are VoipStunt, VoIPCheap, Netappel, SIP Discount, SparVoIP, Internetcalls, VoipDiscount and a few others - the larger more established Broadband phone services should take note.
