Telephone service companies have created a special communication service without the need to use customer's equipment. It's called a "virtual number". It also has a text type of "virtual SMS center." Thanks to the virtual link you can make calls or send messages while connected to the equipment of the company.
Evolutiontel is an Australian owned company specialising in Voice over Internet Protocol (VOIP). Our first project was to provide a VOIP service that allows voice and video calls over the internet without sacrificing quality.
