VoIP Introduction

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.
