VoIP stands for Voice over Internet Protocol. It's how modern business phone systems work — using your internet connection to carry voice calls instead of traditional copper phone lines.
When you speak into a VoIP phone, your voice is digitised into small data packets. These packets travel across your internet connection to a server (either on your premises or in the cloud), which routes them to the recipient. The recipient's phone converts the packets back to sound. The whole process happens in milliseconds — fast enough to feel like a normal phone call.
You need an internet connection (10Mbps+ is sufficient for multiple simultaneous calls), a VoIP phone or softphone (app on PC or mobile), and a cloud PBX account. With hosted VoIP from Telexico, the PBX runs in our data centre — you just need the phones and broadband.
Hosted VoIP (cloud PBX) means Telexico manages all the infrastructure. You pay a monthly per-user fee and access the system via phones and apps. On-premise VoIP means a physical PBX server at your office — higher upfront cost, maintenance required, but more control for large enterprises with IT teams.
Modern VoIP using HD codecs (G.722) produces noticeably better call quality than traditional PSTN. The two variables that affect quality are internet speed (easily met by any business broadband) and jitter/latency (managed by QoS settings on your router — Telexico configures this as standard).
