Why is Voice over IP (VoIP) being used instead of a digital system?
Almost all development within the telecom industry is transitioning to a VoIP type system. The installation of a VoIP system will not only maximize the working life of the system, it will also benefit in future development as new applications become available. For example, use of enhanced audio and video capabilities, as well as ability to make phones more mobile. VoIP also has a lower total cost of ownership.
