What is VoIP?
Voice over Internet Protocol, or simply VoIP, is a cloud telephony system that enables communication like voice calls, video calls, and message services via the Internet. VoIP is a disruptive telecommunication advancement that has changed the way we communicate for the better.
Voice over IP eliminates the hassles of setting up telephone lines and creating communication infrastructure. In short, VoIP calls and messages can be made and received using only a device and an internet connection.
When we think about communication via the internet, Voice over IP appears to be a sophisticated form of communication. However, trust us when we say it has an effortless way of operating.
First, the VoIP system uses “analog-to-digital conversion,” where the analog data from the sender is transmitted into digital data.
After the successful transmission, the data is further transmitted into smaller packets called “VoIP Packets” before being sent over the internet. After the transfer, the digital data is converted back into analog data, which the receiver can use. This process happens simultaneously, and the communication process is rapid.
