When the World Wide Web appeared in front of the public, it transmitted data, texts, photos, etc. via telephone lines. You use the modem connected to the computer, dial the local "access number", and then you can browse the Internet freely. You may need to pay an Internet service provider, but the transmission method is basically just a phone call. In the following years, Internet access via DSL and cable made it possible to transmit large amounts of data quickly, which means that the Internet has a huge data capacity. In short, we are now using the Internet to make calls, and we used to use the telephone to connect to the Internet.
This technology is called Internet Protocol Voice Technology or VoIP . In short, voice is transmitted as data via the Internet. The extension of VoIP is called IP relay, where multiple users with the same Internet connection use VoIP to send and receive Internet and voice data.
VoIP and IP trunking are a big business. This is a new communication framework that is gradually replacing the old telephone company infrastructure. IP relay, also known as "unified communications", will become a valuable business in just a few years. Now is a good time to learn about the new standard for telephony and the details about how computer networks accurately convert voice to data, and then back to voice to create a seamless phone.
