VoIP Introduction
Source: Ziff Davis VoIP uses internet protocol data packets to transfer voice, fax, and other data over the shared network, rather than the traditional public switched telephone network (PSTN), which is based on copper wires carrying analog voice data over the dedicated circuits. VoIP, in contrast to PSTN, uses what is called packet-switched telephony, whereby the voice information travels to its destination in individual network packets across the Internet that are assembled and then converted to voice. Learn the basics of VoIP by reading this white paper, which includes explanations of coding and protocol for VoIP, and a look at quality and myths about VoIP. Read More...

Voice over IP Reliability
Source: ShoreTel, Inc. We all know that computers, generally speaking, have not been as reliable as phones. And the fear, uncertainty, and doubt (FUD) surrounding voice over Internet protocol (VoIP) has been, in some cases, justified. However, for VoIP the question now is not whether reliability can be achieved, but rather how much reliability you can expect from the options available to you. Read More...
Monitoring and Managing Voice over Internet Protocol (VoIP)
