Phones

VoIP is Voice over Internet Protocol. Standard telephone lines are referred to as PSTN or the Public Switched Telephone Network. PSTN works on circuit switching. A good example of circuit switching is the old switchboard operator who would connect callers to receivers by the use of electrical circuits. VoIP is Packet Switching. Packet Switching consists of data packets, or packets of information being carried across the Internet, from your computer to either another computer or PSTN telephone.
