Time to Upgrade from ISDN?: 

Do you still have ISDN? If so, it is time to change.  The traditional PSTN, ISDN2 and ISDN30 lines that have served many of us so well in the past are now outdated, no longer meeting the evolving demands of our digital age and will be retired in 2025. From 5th September this year (2023) they are already no longer available for new provide.

Here’s why now is the perfect time to consider an upgrade, and how HM Network, an award-winning BT Partner, is your ideal choice for this transition.


  1. The Limitations of ISDN

ISDN (Integrated Services Digital Network) was groundbreaking in its time, providing digital voice and data services where traditional analog lines couldn’t. However, its limitations are becoming more evident:

  • Limited Scalability: Scaling up or down with ISDN can be cumbersome and costly. Each time you want to add or remove lines, you are faced with physical constraints and potential delays.
  • Higher Costs: With the ongoing maintenance and rental costs, ISDN often becomes expensive in the long run compared to newer alternatives.
  • End of Life: Openreach are phasing out ISDN lines by 2025 and are already on a “stop sell”. In the very near future, support for these lines will be minimal or completely unavailable.


  1. The Future is IP-based Voice

Migrating to an IP-based voice system is not just about keeping up with the times. It’s about harnessing numerous benefits:

  • Flexibility and Scalability: IP-based systems allow businesses to easily scale up or down based on demand without the hassle of physical line installations.
  • Cost Efficiency: Reduce monthly costs and get better value with feature-rich IP voice solutions.
  • Advanced Features: From video calls to conferencing, CRM integration, and more, modern UCaaS and IP voice solutions offer a wide range of advanced features that are not possible with traditional ISDN lines. We have a range of hosted and SIP options available. 
  • HM Network may be able to help you migrate from an old service or even in some cases, help pay off old contracts so you can make the move sooner.


  1. Why BTnet Dedicated Internet is a great choice
