With the UK’s 2027 switch-off of PSTN and ISDN networks, moving to digital telephony (also known as VoIP or cloud telephony) is a crucial step. This transition not only ensures continuity but also unlocks cost savings, scalability, and advanced features. At Talk Telecom, we help businesses adopt hosted VoIP systems and unified communications that deliver reliability, flexibility, and long-term value.

With the UK’s planned withdrawal of PSTN and ISDN services in January 2027, moving to digital telephony, also known as VoIP or cloud telephony, is becoming essential. This transition not only ensures continuity but also offers long-term cost savings, flexibility and access to modern features. At Talk Telecom, we support businesses in adopting digital phone systems that deliver reliable, scalable and future-ready communications.

What is digital telephony
Digital telephony includes services such as VoIP phone systems, cloud telephony, SIP trunking and IP telephony. It uses the internet rather than traditional copper lines to transmit voice calls, offering better reliability and integration with other digital tools.

Key benefits of switching to digital telephony

1. Cost savings on calls and infrastructure
Digital systems such as hosted VoIP remove the need for on-site PBX hardware and significantly reduce call charges, especially for long-distance and international communication. Businesses also save on ongoing maintenance and infrastructure costs associated with legacy phone systems.

2. Clearer call quality and improved reliability
Digital telephony offers high-definition voice quality and fewer service disruptions when compared with traditional telephony. Talk Telecom’s digital infrastructure includes backup systems and failover routes to keep your communications running without interruption.

3. Greater flexibility and scalability
Cloud-based phone systems make it easy to add or remove users, devices and locations without requiring additional physical infrastructure. This is especially useful for growing businesses and those with remote or hybrid working models.

4. Support for remote and mobile working
Digital telephony allows users to make and receive business calls from anywhere using a desktop computer, mobile app or softphone. This ensures that staff remain connected whether they are in the office, working from home or on the move.

5. Integration with business systems
Modern digital phone systems can connect seamlessly with CRM platforms, collaboration software and call analytics tools. This helps businesses streamline operations, improve customer service and gain useful insights from call data.

6. Stronger security and compliance
VoIP and cloud systems offer secure protocols, encrypted communications and the option to enable call recording. These features support data protection and compliance with UK regulations and industry standards.

7. Preparation for the PSTN switch-off
With BT set to retire all PSTN and ISDN services by the end of 2025, switching to digital telephony now gives your business time to prepare and avoid last-minute disruption. It also opens the door to smarter, more efficient communication tools.
