Voice over IP, or Voice over Internet Protocol to use the full title, is simply a means of making telephone calls over a data network instead of over the traditional analogue public switched telephone network (PSTN).The term VoIP describes the use of the Internet Protocol (IP) to transfer speech between two or more sites. Inherent to the term is the management of the protocol. In general, this means that the voice information is encoded into discrete digital packets and then transferred over an IP-based network.There are many advantages to this method of telephony, primarily the cost savings that can be made by avoiding the use of the traditional PSTN. In addition to cost savings, the digital nature of VoIP allows easy administration, implementation of additional services such as voicemail, and a reduction in the physical cabling required for new installations.

VoIP offers a number of potential advantages and benefits to its users:

• reduced operating cost, including lower telecom charges;
• flexibility;
• reduced infrastructure;
• integrated services and superior user features.

Yes, it is !!!

The switch to VoIP, which has been happening for years, is now accelerating. About 35% of the international carrier calls use VoIP / VoFR / VoATM. These figures do not include calls that are intra-corporate calls carried on WANs but simply calls handled by carriers. Most of the growth in the number of international calls has appeared on VoIP networks; most installations of new capacity have been those of VoIP capacity. All of the North American and European telecom operators take advantage of using VoIP.
