PSTN Switch-off – A Step-By-Step Planning Tool [Guide]

PSTN switch off

The PSTN switch-off affects all UK businesses, often in ways they might not expect. What exactly will it mean for you, and what are your options?

Don’t put off finding out.

FUTURE-PROOFING YOUR TELEPHONY IS ONLY HALF THE STORY
It’s a cliché because it’s true: communication
really is the lifeblood of a business.

Okay, we know: revenue, cash-flow, data, innovation and several others are also worthy candidates… but it’s an inescapable fact that without smooth-functioning communications, most corporations simply can’t function.

Yet for many businesses, that’s exactly what’s at stake right now.

And we’re not just talking about phones and Internet. Upcoming changes to the UK communications infrastructure could easily put the wider workings of your business at risk, from card machines to emergency alarms, lifts, entry systems and much more.


That’s right. We’re talking about the imminent PSTN SWITCH-OFF.


TTFN, PSTN

In the biggest communications shake-up in 30 years, BT will switch off the Public Switched Telephone Network (PSTN), which incorporates conventional phone lines, ISDN, single analogue lines and other connections, by December 2025. This will be preceded by a total “stop-sell” of these services as early as 2023.

What does this mean?

These services will be replaced by “all IP” technologies using Openreach’s fibre network. This means all businesses currently relying on single analogue or ISDN for their calls or broadband will need to migrate to a single-order, fibre-only alternative like Single Order Generic Ethernet Access (SOGEA), through which voice, broadband and other services can be delivered together.

But it’s not just your phone and broadband. Businesses rely on a whole range of other common devices and appliances that use single analogue lines in order to function. If you don’t have an alternative in place by December 2025, these too will cease to function.

HOW TO USE
THIS GUIDE
In these pages, we provide information to help you audit your current communications (and other business-critical technologies) and determine whether (and how) you need to act in each case.

We also provide concrete examples of potential solutions.

There are a number of successor technologies readily available such as SIP and broadband replacement services (over both the Gamma network and Openreach’s full-fibre network), as well as single-user voice replacement products. These technologies will help you to future-proof your communications, give you more options and streamline your costs. The earlier you act, the sooner you’ll benefit.

THE ONLY SURE THING IS: YOU NEED TO ACT.
HERE’S HOW TO DO SO IN A WAY THAT SUITS YOUR BUSINESS AND YOUR CUSTOMERS.

YOUR FUTURE, NOW
BUSINESS TELEPHONY
Option one:

SIP Trunking connected to your current telephony solution (PBX)

What is this?
Daisy can use SIP Trunking to deliver Voice Over Internet Protocol (VoIP) technology directly into your private branch exchange (PBX), enabling high-quality voice calls with existing telephone numbers ported across.

Why might it suit me?
Can be used to future-proof your telephony or upgrade your current unified communications (UC) solution with VoIP, regardless of provider.

What’s necessary to make it work?
Your PBX may need to be upgraded to enable SIP. Daisy can install a Session Border Controller that fits the requirements of your UC supplier, and manage any licensing and software upgrades.

Option two:

SIP Trunking connected through an AudioCodes “ISDN to SIP Converter”What is this?
An alternative way for Daisy to deliver VoIP telephony into your business, enabling high-quality voice calls with existing telephone numbers ported across.

Why might it suit me?
In some cases, your PBX may not allow an upgrade to support SIP, or the cost of doing so might considerably outweigh the cost of an ISDN to SIP converter.

What’s necessary to make it work?
Daisy can install the AudioCodes hardware and, if necessary, reconfigure the programming of any internal systems.

Option three:

Design and deploy a comprehensive new UC solution

What is this?
A completely integrated unified communications solution, with voice calls, instant messaging, video conferencing and other collaboration tools made available to all your people on a single, mobile-friendly app.

Why might it suit me?
All elements of your business communications are brought together in the most efficient way for your particular needs – transforming productivity and scalability while improving the customers’ experience.

What’s necessary to make it work?
Daisy’s specialists can assess your needs and design a solution based on one of the following three models:

  • Combining Microsoft Teams with external voice calling (using direct routing technology)
  • A private cloud solution delivered in collaboration with our partners Mitel, or another UC platform suited to your needs
  • A public cloud solution delivered in collaboration with our partners Gamma, or another UC platform suited to your needs.
YOUR FUTURE, NOW
BROADBAND (ADSL2)
SOGEA full fibre broadband (“to cabinet” or “to premises”)

What is this?
Daisy can supply Single Order Generic Ethernet Access (SOGEA) broadband over both the Gamma network and with a choice of bandwidths over Openreach’s fibre network, either on a “Fibre to the Cabinet” (FTTC) or “Fibre to the Premises” (FTTP) basis, as appropriate to your needs.

Why might it suit me?
Your broadband Internet, as well as other services like VoIP (through our partners Gamma) can be delivered through one single-order fibre connection. As well as being convenient, it’s also likely to be cost-effective.

What’s necessary to make it work?
Your current router may need to be upgraded to accommodate an FTTC or FTTP connection.

OnlineUC Phoneline+

What is this?
This is a cloud-based single-user VoIP service, designed for a single-user environment deployment. Daisy can supply a single-user voice overlay to your SOGEA service to provide both speech and analogue data services like a fax machine.

Why might it suit me?
If you currently use the analogue line element of your broadband service to make voice calls or to support an analogue data service like a fax machine, then this solution will support your future needs.

What’s necessary to make it work?
A SOGEA or appropriate data service, an IP-enabled handset for speech or an ATA for an analogue data service like a fax machine.

YOUR FUTURE, NOW
SINGLE ANALOGUE EXCHANGE LINE
Do you rely on a Single Analogue Exchange Line for any of the essential services listed here?

Then you need to take action.
The services affected by the PSTN switch-off go far beyond voice calls and web connectivity. As well as helping you switch to a SOGEA broadband connection using either Gamma’s network or Openreach’s “full fibre” network, Daisy can help you identify and execute a migration pathway for other services that currently rely on a traditional analogue connection.

DON’T PUT IT OFF…
TAKE THE FIRST STEP
The clock is ticking towards the demise of the PSTN. If you don’t have an alternative fully in place by December 2025, your phones will stop ringing, your lifts and other vital facilities may cease to work and your customers may be cut off from contacting you.

But there’s a far better reason to act now. Businesses who’ve already switched their telephony to SIP Trunking are already saving thousands on their call costs, as well as relaxing in the knowledge that their operations are set for 2025 and beyond.

Whatever stage you’re currently at, Daisy’s specialist team can help you assess your needs and manage a seamless migration that works for you and your customers. Call us today for a no-obligation chat.

Because the best time to act is always now.
