The change is more important than just converting the earlier used system of time division multiplexing or TDM to Internet Protocol or IP. This is the first step of companies to solve difficulties regarding costs and achieving business goals of the organization. Apart from voice the architecture that is used with IP communications include "video, messaging, contact centers and business process enablement".

This is being transmitted for quite some time now and dependable channels have already been developed. The costs of this method are also viewed to be quite low, and that will naturally reduce costs of transmitting voice.
