Once upon a time VoIP was just a way for the extremely pc smart to save a few dollars by making pc to pc "phone calls" to a restricted group of friends who were running the same application and had a mic and a set of sound system or a earphone. Go forward to recent times where VoIP provides cost-effective cellphone alternatives for customers from all avenues of life and can provide a edge against their competitors for companies, especially little companies.
