What is IP telephony?

IP telephony is a telephone communications service that uses the Internet Protocol (IP) to transmit voice and data over the Internet instead of using traditional telephone lines. This telephony communicates by digital means through the network using VOIP or Voice IP, and has become the communication service most used by most companies in the world due to its low cost of implementation and quality.


How does IP Telephony work?


The process of operating IP telephony is relatively simple. When we make a call, our voice is converted into digital data that is compressed and sent in packets over the Internet or through a local IP network between IP phones in a telephone exchange. These packets are transmitted through routers and servers until they reach the recipient of the call.Once the packets reach the recipient, they are decompressed and converted back into voice signals so that the recipient can hear our voice clearly. All this process occurs in real time, which allows fluid communication without perceptible delays.
