The Impact of the 2025 BT Switch Off on Your Business: What You Need to Know

Embracing the Future: The 2025 BT Switch Off

As we move closer to 2025, a significant shift in the UK's telecommunications landscape is on the horizon. The BT switch off, a nationwide transition from analogue to digital technology, is set to revolutionize how we communicate. This change, led by BT and overseen by Ofcom, marks a pivotal move towards more reliable, efficient, and future-proof communication systems.

Understanding the Switch Off

The switch-off involves retiring the Public Switched Telephone Network (PSTN) and its associated services like ISDN lines, affecting numerous businesses and households across the UK. This transition is not just a technical upgrade; it's a complete shift in the communication paradigm, moving away from the century-old copper wire system to a more advanced digital network.

Why the Change?

This change is driven by the need for a more robust and versatile communication infrastructure. The existing copper network, with parts over 140 years old, is no longer sustainable. The digital switch ensures faster, more reliable connections, paving the way for innovative communication solutions.

Impact on Businesses

  • Telephony Services: Traditional telephone systems and fax machines will become obsolete. Businesses will need to adopt SIP trunking or cloud-based telephony solutions.
  • Broadband Services: The switch-off necessitates the move to fibre broadband or Single Order Generic Ethernet Access (SoGEA) where fibre is not available.
  • Special Applications: Services like alarm lines and payment terminals that currently rely on PSTN will need to be compatible with new IP technology standards.

Preparing for the Transition

To ensure a smooth transition, businesses should start planning now. This involves evaluating current telephony and broadband setups and consulting with IT and telecom experts to understand the best options. Implementing the necessary changes well ahead of the deadline is crucial.

Change Mac's Default Calling App for Telephone Links

Change Your Mac's Default Calling App

It might seem surprising, but to change this setting, you actually need to navigate to FaceTime. It's a typical Apple approach, requiring users to go through their own app to modify default behaviours for such services.

  1. Open FaceTime: Locate and open the FaceTime app on your Mac, either through the Spotlight search or in the Applications folder.
  2. Sign In: Log in with your Apple ID to access the settings.
  3. Go to Preferences: In the FaceTime menu, choose "Preferences" to open the settings window.
  4. Select New Default App: Under the "Settings" tab, find "Default for calls." Use the drop-down menu to pick your preferred calling app, like 8x8, Webex, or RingCentral.
  5. Confirm Changes: Close the Preferences window to save your new default calling app.

Pete's Tips for Enhanced Control and Privacy

  • Disable and Sign Out: After setting your preferred app, remember to untick "Enable this Account" in FaceTime settings for added privacy. Then, sign out to keep your information separate from Apple services.
  • Same Steps for Apple Mail: You can use a similar process to change your default email client in Apple Mail. It’s all about customising your Mac to suit your workflow.


Changing your default calling app on a Mac is a simple process that can significantly improve your communication efficiency. Whether it's for privacy concerns or a preference for specific services like 8x8, Webex, or RingCentral, these steps will help you align your Mac with your professional needs.
