The Big Switch: Why your business needs to move to Internet Telephony

If your business is still relying on old-school phone lines, you need to pay attention. By the end of 2027, traditional landlines (PSTN and ISDN) are being switched off for good. That means if you haven’t moved to a modern system by then, your phones could just… stop working.

Don’t panic - it’s not complicated. The solution? Internet telephony.

So, what’s Internet Telephony?

Think of it like your phone line, but smarter. Instead of sending your calls through old copper cables, everything - voice, video, voicemail, even faxes - travels digitally over the internet. Fast, flexible, and reliable.

How it works (without getting too techy)

When you speak or start a video call, your voice and video are turned into tiny data packets. These packets zip across the internet, reassemble at the other end, and voilà - your colleague or client hears and sees you clearly.

And yes, VoIP (Voice over Internet Protocol) is part of this - it’s just the voice-focused side of internet telephony.

What you need to get started

Good news: it’s simple. You need:

• A solid internet connection

• A device to make calls (laptop, phone, tablet, or a desktop phone)

• Optional: a headset for crystal-clear audio

Some businesses still love desk phones - but today’s versions are packed with features that old lines could never offer.

Why you can’t wait

This isn’t just about cost or convenience (though those are big perks). It’s about survival. Analogue phone lines are going away, and you don’t want to be scrambling at the last minute.

What makes Internet Telephony better?

Flexibility – Take calls anywhere, on any device. Need to redirect a call? You can do it in seconds, no waiting for a provider.

Scalability – Growing team? Busy season? Add or remove lines instantly. No extra hardware required.

Cost Savings – Calls over the internet are cheaper, and features like voicemail, conferencing, and call forwarding are included. No pricey add-ons.

Clearer Calls – With a fast internet connection, say goodbye to dropped calls and delays.

Business Continuity – Cloud-based systems mean calls keep going even if your office power goes out. Home workers, branch offices, and remote teams stay connected.

The switch-off is coming. The sooner you act, the smoother the transition will be. Start exploring internet telephony now - your business will thank you with clearer calls, happier customers, and zero last-minute stress.
