2025 will see the end of BT’s PSTN and ISDN services. However, businesses that value commercial relevance and productivity will make the move to a VoIP solution long before the switch off.

BT will switch off its PSTN and ISDN networks in 2025, in favour of VoIP (Voice over Internet Protocol) telephony solutions. This will begin with the phasing out of BT’s older systems from 2020 and BT will also cease taking ISDN telephone orders.
If you haven’t switched to a VoIP solution, or have yet to consider it, the time to do so is now.

What are ISDN and PTSN and why are they being switched off?

PSTN (Public Switched Telephone Network) is the traditional landline telephone system originally set up for analogue voice communication. When ISDN (Integrated Services Digital Network) was introduced, it allowed for the digital transmission of voice, video and other data and services over phone lines.

Currently being phased out, these services still utilise the same costly and problematic design and set up that has existed for well over 100 years. With VoIP solutions now developed to be a truly superior alternative, BT have decided to focus on them solely hence the ISDN switch off.

What is VoIP?

In the simplest terms, VoIP (Voice over Internet Protocol) allows you to make voice and multimedia calls over an internet connection using computers, handsets, mobiles and other smart devices.

How does VoIP provide a better telephony experience?

Whilst providing the practical features of traditional business telephony, such as voicemail and the holding, forwarding and transferring of calls, VoIP solutions also deliver a variety of additional functionality, benefits and potential.

• Cost reduction – one of the most substantial differences between ISDN and VoIP solutions is cost. Between VoIP users on the same network, communications are often completely free. Furthermore, the setup and ongoing costs are typically much less than traditional telephone systems.
• Mobile devices – with VoIP, mobile devices can integrate with your onsite office phone system. It allows you to carry with you a full-featured business phone system in your pocket, wherever you go.
• Reliability – connection quality and consistency of service are both excellent with a VoIP solution. However, in addition to this, VoIP also provides easy and quick disaster recovery. Following a destructive event, such as a fire, your numbers and programming can be moved seamlessly.
• Flexibility – adjusting the customer journey through your phone system is simple, so you can develop and improve your customer telephone experience with ease. VoIP systems are also easily scaled, allowing you to expand or contract the number of devices within your phone system at low cost and minimal disruption, in a short timeframe.
• Recording and reporting – VoIP systems can provide real-time reporting and call recordings which allow you to monitor activity and performance as well as effectively manage all your telephone communications.
• Integration with your IT – with a VoIP telephone system your telephony can integrate seamlessly with your IT, putting customer information at your fingertips. This allows you to enhance the user experience of your staff and the service quality of your customers.
