What is VoIP networking?
Voice over Internet Protocol (VoIP), is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line.
How do phone calls work?
How do cell phones work? A microchip in the phone modulates (or varies) a radio wave using the electrical signal. The radio wave travels through the air to a nearby cell tower; the tower sends your voice to the person you are calling and the process is reversed so that the person on the other end can hear your voice.
What protocol does VoIP use?
the Internet Protocol (IP)
Voice over IP (VOIP) uses the Internet Protocol (IP) to transmit voice as packets over an IP network. So VOIP can be achieved on any data network that uses IP, like Internet, Intranets and Local Area Networks (LAN).

How are calls made?
How cellphone calls travel. When you speak into a cellphone, a tiny microphone in the handset converts the up-and-down sounds of your voice into a corresponding up-and-down pattern of electrical signals. A microchip inside the phone turns these signals into strings of numbers.
Which of the following is a commonly used protocol for VoIP network communication?
The most popular protocols currently used by VoIP or SIP (Session Initiation Protocol) and H. 323. Most of the VoIP providers will offer SIP trunking capabilities. Beyond this, VoIP can implement other protocols such as MGCP and SCCP.
Are phone calls TCP or UDP?
Call Quality Once the phones are registered and a call is set up, it’s time for UDP to take center stage. A phone conversation is a stream of packets meant to be created, sent, and received in real time. With TCP, a lag—any lag—would mean a degradation in the quality of the phone call.
