Hello T1success,

VOIP and IP Telephony are closely related and in fact IP Telephony is dependent upon VoIP. VoIP is the building block for delivering conversations over an IP network. That network is typically a data network for an enterprise that has been converged together with a private voice network in the hope that a lower cost of operation would be achieved. But without the means to manage the traffic, assure the quality of the conversation, enable the end user to control the calls with advanced business features that they have grown accustomed to using at work, then the enterprise will not be pleased with the VoIP experience. The surrounding assurances, call controls, security, and features that differentiate an IP Telephony call with one that is just using VoIP.

Data traffic crosses over a network much like a freight train delivers cargo from a point of origin to a destination. As long as the delivery is made, it does not matter how comfortable the ride or how delayed it was, as long as it arrives intact at the destination. VoIP delivers voice as packets across a network in a train-like manner, vulnerable to jitter, delays, and interruptions.

Voice needs to travel in a much more comfortable manner. It needs alternative paths to guarantee continuous flow of packets regardless of the congestion on the network. Much like driving a luxury sports car, IP Telephony facilitates the delivery of voice packets across the network with speed, plenty of options, and gives the caller control over the experience.

IP Telephony unites an organization's many locations - including mobile workers - into a single converged network. It provides cost savings by combining voice and data on one network that can be centrally maintained, as well as by eliminating toll expenses for calls between locations.
