Voice Over Internet Protocol VoIP

What Is VoIP?

Voice Over Internet Protocol (VoIP) is a technology that allows users to make voice calls using the internet instead of the conventional telephone network. At its core, VoIP transforms analog voice signals into digital data packets that can be transmitted over the internet. This means that rather than relying on traditional telephone lines, calls can be made through broadband connections, and often at significantly lower costs as office phones.

How VoIP Works

VoIP operates by utilizing a set of protocols that facilitate the transmission of voice data. When a user speaks into a microphone, their voice is converted into digital signals, which are then compressed and transmitted over the internet. On the receiving end, this digital data is decompressed, transforming it back into audible sound through speakers or headphones.

The most commonly used protocols in VoIP include SIP (Session Initiation Protocol) and RTP (Real-time Transport Protocol). SIP handles the signalling and setup of phone calls, while RTP is responsible for delivering the voice data in real-time. This efficient data exchange allows for clear and timely conversations.
