VoIP (Voice over Internet Protocol) is the technology that lets you make phone calls over the internet instead of a traditional phone line. It powers cheap international calling, browser-based dialers, and most modern business phone systems.
How VoIP works
Instead of sending your voice down a copper wire, VoIP converts it into small packets of data and sends them over the internet. At the other end, those packets are turned back into sound. When you call a real phone number, a gateway connects your internet call to the public phone network so the recipient just hears a normal call.
Why people use VoIP
- Lower cost - internet calls avoid expensive carrier long-distance fees.
- No hardware - you can call from a browser, app, or desk phone.
- Global reach - call any country at per-minute rates that are shown upfront.
- Extra features - recording, transcripts, and live translation are easy to add.
VoIP and Localcall
Localcall is a browser-based VoIP service: it connects your browser to the phone network with WebRTC, shows the per-minute rate before you dial, and can translate the call in real time. There is no app to install and you pay only for the minutes you talk.
