ISDN SWITCH OFF:
WHAT WILL REPLACE IT?

Did you know the UK is set to switch off ISDN phone lines by 2025?

ISDN and PSTN circuits will be switched off and customers will move over to VoIP telephone systems.

The demise of ISDN certainly isn’t negative for business though. VoIP systems, the alternative to ISDN and PSTN deliver many benefits. VoIP will transform your comms for the better both now and into the future whilst providing cost and productivity advantages. It’s time to think about switching now – fill in the form below to see how we can help.

WHAT IS THE ISDN SWITCH OFF?

The ISDN switch-off refers to the process of discontinuing the use and support of ISDN technology by telecommunications companies in favour of more modern and advanced technologies powered by broadband internet.

Many UK businesses are still using the ISDN system and will require upgrade to a newer system before the end date.

WHEN WILL ISDN BE SWITCHED OFF?

The current set date of the ISDN switch off is December 2025. We do not expect any delays to this date at this point but will update if any are announced.

WHAT ARE THE RISKS OF THE ISDN SWITCH OFF?

The largest risk facing businesses around the subject of the ISDN switch off is complete loss of phone communication. If a businesses are not prepared before the switch off date they might find that they’re at a back of a long queue of instillations whilst also having no telephone system. This could cost businesses customers and revenue.

WILL ANYTHING ELSE BE AFFECTED BY THE ISDN SWITCH OFF?

Some CCTV and Alarm systems use the ISDN / PSTN network and might be affected by the ISDN switch off. Get in contact with your providers to ensure your business is still protected.

STILL USING ISDN?

FIND OUT HOW WE CAN HELP

WHAT ARE PSTN AND ISDN?

Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN) are the circuits that most of us currently use to communicate over the phone.
PSTN is an older technology operating using the same principles as the first ever public phone network. ISDN uses more recent technology to deliver both voice and data services over digital lines at the same time. It was once the go-to option, but it’s now showing its age and is increasingly not fit for purpose.

WHAT WILL REPLACE ISDN AND PSTN?

In short, PSTN and ISDN circuits will be replaced by VoIP (Voice over Internet Protocol) systems.
To make the switch, your business can either opt to move to a new hosted system or, upgrade your existing system so you can connect it to your broadband connection. The switch is simple and will deliver many benefits to your business.

VoIP – VOICE OVER INTERNET PROTOCOL

WHAT IS VoIP?

VoIP allows users to make and receive calls using the internet it converts voice comms into digital data that travels over an internet connection to its destination.
Calls can be made with any device that has a reliable internet connection, including a desktop computer, laptop, smartphone, or tablet. Extensive business features give users incredible flexibility to make and receive calls from anywhere without being dependent on a physical location like a traditional desk phone.

THE BENEFITS OF VoIP

CALL QUALITY

Call quality is arguably the most important factor to consider when choosing a phone system. Enjoy the crystal clear calls that are vital for your business.

MULTI-FUNCTIONALITY

Delivers many more features than traditional phone systems. They offer other communication services such as: instant messaging, teleconferencing and video calls.

SECURITY

Security against telecoms fraud is vital for every business. VoIP offers you more protection as it’s far more secure than traditional analogue telephone connections.

PORTABILITY

With the number of remote workers increasing at a rapid rate flexibility is essential. VoIP phones offer portability as they can be used anywhere so they are ideal for remote working.

FEATURE PACKED

VoIP phone systems come with a lot of added extras as standard, compared to traditional phone systems. These features were created to make processes easier and more automated.

COST EFFECTIVE

The system is cheaper to purchase and install with very little hardware costs. In addition, call costs are significantly cheaper when compared to traditional phone systems.

YOUR QUESTIONS ANSWERED
What is a business phone system and what equipment do you need?

A business telephone system is a phone system which improves your company’s ability to communicate at scale.

Traditional phone systems are built using analogue technology, this system is expensive and lacks features which modern businesses require to be successful.


Modern features such as:

  • Multi line holding
  • Auto attendant
  • Download Voicemails
  • Call recording
  • CRM software connections
  • Mobile integration

Modern day VoIP business phone systems use the Internet instead of a landline to transfer voice data at a much faster speed and at a lower cost.

The system is made up of a phone, computer, internet connection and a PBX box either hosted in the office or on the cloud. Cloud hosted PBX boxes help businesses become more dynamic with their work allowing for employees to work from home whilst retaining an office phone number and all the system features.

Will I lose my number with the ISDN switch off?

No, if you transfer your number to a new VoIP system you can almost always transfer your current number.

How do I install the new business phones?

Depending on the phone system you choose we have many options to help you install the phones.

In many cases the system will be a simple plug and play. If you occur problems our support team have exceptional facilities to live video guide you through installation.

We provide free on site support for large installations or issues unresolvable by call/video.

  • “Review for Louise Childs This review and the quality of my experience is in relation to our interaction with Louise Childs. Every time we needed to contact her, she has responded swiftly and done her best to solve the matter herself or with the help with one of her colleagues (depending on the nature of the problem). There are some teething issues with Enrich that homely will be resolved sooner rather than later. Thank you Louise for all your endeavours.”
