Whether you’re a business owner, IT professional, or an individual user, understanding the implications of the ISDN & PSTN switch off is crucial to maintaining uninterrupted communication services.

If you are one of the many businesses who do not yet know about the switch off, you can find out everything you need to know in our comprehensive guide.

When BT switch off the ISDN & PSTN networks (the traditional cable telephone lines) in 2025, all phones must operate digitally over the internet. This will be done using a VoIP phone system rather than a traditional landline.

If your business does not currently operate with a VoIP system, it’s essential to start preparing your business for the PSTN switch off now.

Here are some steps to help you get ready:

1. Assess your current telephony setup: Take a look at your existing phone systems, devices, and services that rely on PSTN or ISDN. Make a list of everything that will be affected by the switch off.
2. Research VoIP providers: Start researching VoIP providers and their offerings. Look for providers that offer quality, trustworthiness, excellent customer service, convenience, and reliability.
3. Plan your transition: Develop a timeline for transitioning from PSTN to VoIP. This should include milestones for upgrading devices, training staff, and implementing new systems.
4. Upgrade devices and systems: Begin upgrading devices and systems that rely on PSTN, such as fax machines, security systems, fire alarms, and retail payment terminals.
5. Train your staff: Ensure your employees are familiar with the new VoIP systems and devices. Offer training sessions and resources to help them adapt to the change.
6. Test your new setup: Before the PSTN switch off, test your new VoIP systems and devices to ensure they are functioning correctly and efficiently.
7. Monitor and adjust: After the switch off, continue to monitor your new VoIP systems and make any necessary adjustments to ensure optimal performance.

The ISDN & PSTN switch off is a significant change in the telecommunications industry, but it presents an opportunity for businesses to upgrade to more modern, efficient, and cost-effective VoIP systems.

By preparing your business now, you can ensure a smooth transition and continue to discover the power of connectivity.
