The Concise Guide to Voice over IP

VoIP, or Voice over Internet Protocol, is the standard used in IP telephony to manage the delivery of voice information using the Internet. IP telephony refers to the array of communication services that are transported via the Internet. VoIP technology eliminates the need for the PSTN, telephone communications as we know it today, and opts for voice, fax, and voice messaging via Internet lines -- therefore eliminating long-distance charges. It's a technology that is emerging out of its infancy and promises to change the face of telephone communications in the near future.The Concise Guide to Voice over IP starts with the basics of digitizing voice signals and explores some of the more common technologies, topologies, and configurations used to support VoIP. It then goes far beyond VoIP by exploring the impending evolution of today's curcuit-switched telephone networks to a packet-switched network that will be technologically indistinguishable form the Internet -- resulting in true IP telephony. But there are many issues and problems that must be solved before IP telephony can become a reality.
