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.
VoIP operates in different forms. For instance, you can use VoIP when you use an Instant Messaging program with voice on your computer. These are very popular and now Yahoo, AOL, MSN, ICQ, and even Google have VoIP Instant Messaging programs. The benefits of these programs are that they are free to download off of the Internet, and by using a microphone and your speakers; you can talk over the Internet with any of your buddies. As long as your friends and family members download the same program, you will be able to talk with them as long as you like, and absolutely free. You can talk to anyone, anywhere in the world with VoIP Instant Messengers.
Another method of VoIP technology is to use a VoIP service provider for your basic telephony needs. A very familiar company is Vonage. For a monthly fee, you will receive VoIP services, the same as you pay for your regular telephone services. You can choose to use your VoIP service over the Internet, or you can choose to connect your VoIP to your standard telephone. By connecting a VoIP phone adapter to your modem and standard phone, you will be able to use your VoIP service and your telephone as you would with any other telephone service provider.Â
