What is VoIP?
Voice over Internet Protocol enables transmission of voice traffic over a packet-switched IP (Internet Protocol) network.
A VoIP Network carries converged voice and data traffic from a public carrier network, the Internet, or private IP intranets.
Companies can develop a Voice over IP architecture in one of three ways:
- By IP-enabling an existing telephony network
- By voice-enabling an existing IP or other packet network
- By building a pure IP telephony network from scratch
VoIP can save toll charges on long-distance and international calls. Today, with rapidly advancing technologies, voice quality on managed VoIP networks can match the public voice network.
The term "Internet telephony" generally refers to Voice over IP services transported over a public Internet backbone but the terms are often used interchangeably
