Introduction:
In recent years, communication technology has evolved rapidly, leading to the phasing out of outdated systems like ISDN (Integrated Services Digital Network). BT has announced that ISDN lines can be purchased up until September 2023, with a forced migration phase between April and December 2025. As a business owner, it's crucial to understand these changes and explore alternative options to ensure seamless communication for your company's growth
Even though you have been given a few more years to be able to purchase more ISDN lines, we still advise that if your telephony contract is up for renewal you start exploring alternatives as ISDN is old technology and will soon be obsolete. If your contract will still be live after 2023 you should ensure you have enough ISDN phone lines to cope with your growth plans.

Why is ISDN being switched off?
The switch-off of ISDN is a result of the evolution of communication technology. BT recognizes that IP (Internet Protocol) is the future, offering greater benefits to businesses. By discontinuing ISDN, BT can focus on investing in newer and more efficient technologies, making it clear that businesses should start considering alternatives.
Embrace the Future: SIP and Hosted VoIP Systems
As the ISDN era comes to a close, businesses have two primary alternatives to consider: SIP (Session Initiation Protocol) and Hosted VoIP (Voice over Internet Protocol) systems. These options offer flexibility, cost-effectiveness, and scalability, ensuring that your business stays ahead in the competitive landscape.
You have a few options but the main 2 are Sip and Hosted VoIP systems:
SIP (Session Initiation Protocol)
SIP uses virtual phone lines instead of physical ones, offering significant advantages for businesses with on-premise phone systems. The benefits of SIP include:
- Flexibility: Easily add or remove phone lines to match your business's changing needs.
- Call Quality: Enjoy superior call quality compared to traditional ISDN lines.
- Lower Call Costs: SIP generally offers lower call costs, helping you save money.
- Compatibility: In most cases, you won't need to replace your existing phone system, as many systems are compatible with SIP.

Hosted VoIP (Voice over Internet Protocol)
For businesses that don't want to commit to an on-premise phone system, Hosted VoIP is an excellent solution. Hosted VoIP uses internet lines and offers the following advantages:
- Scalability: Easily scale your phone system as your business grows without additional maintenance charges.
- Cost-Effective: Avoid the need for expensive hardware and maintenance, as the system is hosted by a service provider.
- Remote Work Friendly: Enable seamless communication for remote and mobile employees.

Migration Made Easy:
Migrating to SIP or Hosted VoIP can be a smooth process with the right provider. You can typically retain your existing phone numbers, and the migration can take as little as three weeks, depending on the complexity and number of sites involved. The whole migration (depending on some factors like the number of sites) can take as little as 3 weeks.
