What's happening to Phonelines in 2025?

Phone lines are changing.

Phone services including

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

are being replaced by an Internet Protocol based lines, systems that use them will have to be bought up to date.

Businesses need to review their Phone Lines and make changes before 2025 to ensure they stay connected.

This is a great opportunity, but you must act now to avoid disruption to your business.

Traditional UK phone lines including PSTN & ISDN are being phased out by 2025.

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

IP or Internet Protocol is the networking technology behind the internet.

PSTN switch-off

Don’t forget that between 2023 and the end of 2025 all broadband solutions based on PSTN and ISDN will need to be upgraded due to the PSTN switch-off.

We will recommend modern digital services whenever they are available.

SOGEA means that you can now order xDSL Business Broadband services, however, you no longer need to take a separate phone line. This reduces the cost by about £12 per month.

The low cost of SOGEA makes it an ideal small business internet solution, which we are happy to recommend.

If you are wondering SOGEA, stands for Single Order Generic Ethernet Access, thanks to the guys at BT Openreach for coming up with that one.

In a nutshell, SOGEA makes existing broadband services suitable for use after the PSTN switch-off as they are services without Voice services included.

Fibre Leased Lines

Fibre leased lines have traditionally been reserved for larger businesses, however, the leased line cost has come down so much over the years that a leased line is a viable option for any business that needs fast synchronous internet.

Asynchronous and Synchronous Internet Connectivity
Business broadband often provides faster download than upload speeds this is what puts the Asynchronous into ADSL. This works well where most of the traffic is being downloaded, like web browsing watching videos etc.

Fibre Leased lines provide a Synchronous internet connection where the upload speed is the same as the download. This is required where as well as downloading you are also uploading a similar amount. This could be from many email accounts, saving large documents to online services, any kind of web hosting and of course if performing online data backups.
