The Big 2025 Switch Off

For those of us who are old enough to remember, the sound of dial-up internet is a distant, and maybe not so fond, memory. The digital world is ever-advancing, so much so that the time is coming for us to say goodbye to PSTN (public switched telephone network) and ISDN (integrated services digital network) altogether. 

PSTN is the familiar landline system originally setup for analogue voice communication, and later became the main carrier for internet activity across the world. Since then, we developed ISDN (Integrated Services Digital Network), which allowed us to digitally transmit voice, video and other services simultaneously, using the traditional PSTN network.

They served us well, and although there have been countless updates to the networks, the time has come for change. However, according to Ofcom, in 2017 there were over two million businesses still with an ISDN connection in the UK. All of these businesses will be affected by the big 2025 switch-off so make sure your business is prepared. Get ready now by switching to an IP-based service such as SIP and VoIP, and avoid being stranded without a phone system.

So what are these new IP-based services? Session Initiation Protocol (SIP) is a protocol used in Voice over Internet Protocol (VoIP). It allows users to make global voice and video calls, using an internet connection. The most prominent difference between traditional ISDN and SIP networks is the flexibility of not being tied down to a fixed line at a fixed location. This allows you to manage your businesses anywhere, ensuring maximum flexibility and efficiency.

Switching could also save you money. It is vital that you choose your internet provider carefully, to ensure their level of services are right for you. You will want a high quality data connection for uninterrupted calls, as well as quality of service. The best suppliers will take care of the porting process for you and should be able to manage the entire process of switching from ISDN to IP. This is essential if your business is to avoid any losses throughout the process. 

This may sound like a lot of information to digest, but help is out there. Although the switch-off isn’t until 2025, it is best to take action now, so you are prepared, and can focus on what really matters - your business.
