VoIP in a Nutshell: Your Granddad-Not Phone System

VoIP is just sending your voice data packets over the internet instead of the phone lines. Imagine your voice as a digital courier hopping the web, no middleman – no copper wire, no vast call charges.

The traditional landlines in the UK work with PSTN (Public Switched Telephone Network). That old technology has been here for centuries- physical lines, heavy switches, and overpriced equipment. It is indeed reliable, but at the same time expensive and restricted to physical limitations.

This is what’s going on:

Cost: Phone lines are charged with expensive contracts and per-minute rates. VoIP can reduce those costs up to 50%.
Features: VoIP brings live video calling, conferencing, voicemail to email, mobile apps- all in one place. You get the idea. Landlines? Just ringing and hoping.
Flexibility: VoIP can be used anywhere where there is internet access making it ideal for remote working. Landlines? Good luck without the help of an electrician trying to move!
Setup: Phone lines require handsets and wiring. VoIP requires just your internet and a device.
Scalability: You may add or delete users instantly on VoIP; no landline provider phone calls, stalled time, nor any fees.

Maybe you are still convinced your landline is enough? Listen… The cleartwo VoIP phone system is the only way to go without worries, you won’t get stuck talking to dead wires in 2026.

VoIP in a Nutshell: Plain and Simple

Want the technical info but no techno-babble? No problem. When you talk into a VoIP phone, your voice changes from the analog (the signal of old phones) to digital data. The internet doesn’t andcan’t process voice; it doesn’t like it. It dictates that there must be only data packets flowing.

These packets break your voice into tiny sound pieces, sent one by one via the internet packet switching – just like your Netflix streaming and chocolate memes loading. After wandering around, the packets finally find the fastest route and arrive at the destination where they are combined and transformed back into sound.

And that is not all. VoIP runs via the internet, not the telephone lines, therefore it can easily interface with other apps, software, and web services like it’s a walk in the park.

The main parts here are SIP (Session Initiation Protocol) and RTP (Real-Time Protocol). SIP is the organizer of the party who sets up the call while RTP is the driver who delivers the voice data.

If your broadband is slower than dial-up, expect to drop calls or sound like a robot. Just upgrade already.

For the full-no fluff-get serious perspective, read cleartwo’s VoIP core communications. It will not take your time.

Codecs and Your Voice Quality

Are you excited about how your voice can stay clear while it is broken into packets? That’s the codecs algorithms that compress and decompress your voice data. They maintain quality versus data use.

Common UK codecs: G.711 for high quality ( but data-hungry) and G.729 for data-saving with a little fuzziness. The modern systems manage them in real-time depending on your connection.

For a technical view of how SIP and RTP maintain the clarity of the calls, here is a link to Wikipedia’s VoIP page.
