How to Prepare Your Business for Digital Telephony

Ever stood in an endless line at a popular amusement park, watching ride after ride pass you by?  

Waiting until the last moment to switch from the Public Switched Telephone Network (PSTN) could leave your business in a similar standstill. Transitioning early skips the long wait, ensuring your company enjoys the ride towards more advanced, efficient communication solutions. 

As we navigate deeper into the digital era, embracing the rapid pace of technological innovation becomes crucial. One significant change on the horizon is the telecom industry's move away from the Public Switched Telephone Network (PSTN), set to conclude by the end of 2025. This shift marks a pivotal transformation, particularly affecting businesses reliant on traditional telephony services. By focusing now on the advantages that digital connectivity offers, your business can prepare to leverage these new opportunities effectively. 

Here's what you need to know to stay ahead of the switch-off and what it means for your business. Stay to the end for 5 Steps to get ahead of the queue for the PSTN Switch-Off: 

What is PSTN and “the PSTN Switch-Off”? 

The PSTN switch-off is the gradual phasing out of the traditional analog telephone network, known as the Public Switched Telephone Network (PSTN), in favour of a fully digital system. By December 2025, these traditional systems are set to be completely retired, a change driven by the advancements in digital communication technology and the need for more efficient, scalable, and cost-effective alternatives.  

This shift will affect not only landline telephones but also other services that depend on the PSTN infrastructure, such a fax machines, old home security systems, and emergency service lines and any home or work analog devices.

The Timeline & Why It’s Happening 

The transition began with the cessation of new PSTN-based service sales in September 2023, culminating in the full switch-off by December 2025. This shift is driven by the obsolescence of the PSTN and the cost-efficiency, enhanced features, and better scalability of digital solutions like VoIP (Voice over Internet Protocol) present. 

What Does It Mean for Your Business? 

The switch-off indicates that businesses will have to move to digital telephony systems such as VoIP or SIP (Session Initiation Protocol) that operate over the internet. If your business uses landlines, ISDN, or PSTN-based broadband services, you'll need to transition to modern equivalents. The change also extends to other PSTN-utilising services like fax machines, alarm systems, and elevator emergency lines. 

There are numerous benefits of switching to digital early:  

  1. Cost savings
  2. Enables hybrid working with enhanced flexibility
  3. Scalability & future proofing 
  4. Increased reliability and security 
  5. Smooth transition 
  6. Better security features  
  7. Compliance
