What's changes are happening to UK Phone Lines?

Phone lines are changing. UK businesses must transition to a modern telephone system by 2025 as the country's PSTN and ISDN networks are being discontinued.

Traditional phone lines like PSTN & ISDN will no longer be in use after 2025.

After 2025 all phone lines will be IP based, which means that calls are being made across a secure internet connection.

All phone lines will now operate on IP technology, ensuring calls are secure over the internet. Phone services are evolving to Internet Protocol-based lines, requiring systems to be updated.

Phone services impacted by this include:

  • PSTN (Public Switched Telephone Network)
  • ISDN (Integrated Services Digital Network)

Businesses should review their telephone systems before 2025 to stay connected and prevent disruptions.

Acting promptly is crucial to take full advantage of this opportunity.

Internet Protocol (IP) is the technology that powers the internet.
