The Big ISDN and PSTN Switch Off 2025

The future is around the corner – 2025 will bring us Microwave Power Plants1, the founding of U.S.R2 and the end of Integrated Services Digital Network (ISDN) and Public Switched Telephone Network (PSTN) services. So whilst the latter may not be as sensational as the rest, it still spells a fundamental change to the way UK organisations will need to operate.

Goodbye old telephone network.
Hello new opportunities!

Download our guide to find out all the information you’ll need to navigate this landmark change in technology. (In a nutshell, it means you won’t be able to order new ISDN or PSTN services in the UK come 2023, and in 2025 Openreach will cease to provide dial tones or power to the lines which all equals: No. More. Calls.) We are working with Ofcom, communications providers, the Office of the Telecommunications Adjudicator (OTA), the Network Interoperability Consultative Committee (NICC) and trade bodies, to ensure where possible you experience a smooth migration.
Essentially, you need to start thinking of alternatives and changing the way your organisation communicates. There are options already available such as Voice over Internet Protocol (VoIP), which uses data networks to provide you with the same voice service but delivered in a slightly more modern way. It also means you can take advantage of more up to date collaboration tools.
Well, in the same way you probably wouldn’t rely on a car made over 30 years ago to get you to and from work every day, that’s pretty much what your voice traffic has been doing. Everything else has moved on – and now it is time for telecoms to catch up.
Not in the slightest. Daisy has been deploying VoIP services for more than 10 years now (we said it is time for telecoms to catch up). So trust us when we say that the sooner you start considering your options, the easier the transition will be for your business to start taking advantage of the opportunities that solutions such as VoIP can bring.

We know every organisation is different, that’s why we’ll ensure you get the support you and your business need to make an informed decision about your future – be that with an on-premise communications platform, deploying Session Initiated Protocol (SIP) connectivity or going the whole hog and moving to a fully-hosted cloud infrastructure.

Daisy offers an entire range of business-grade broadband and fibre options, alongside dedicated connectivity using Ethernet technology. We will work with you to provide the best option based on your business requirements. Take a look here.
