“Oh, I didn’t know you did telephony!” is something that we hear our clients say quite often! But yes, we do telephony! If you already trust us for your IT support, it makes perfect sense to have us manage your business phone systems too. After all, IT and telephony go hand in hand, and we’re here to make sure everything runs smoothly.

ISDN & PSTN: The Switch-Off is Coming
Let’s talk about something big on the horizon: BT’s switch-off of ISDN and PSTN analogue networks. Originally set for later this year, it’s now been pushed to January 2027. That might seem like ages away, but if your business is still relying on traditional phone lines, it’s worth planning your move sooner rather than later.
This switch-off isn’t just a technical change—it’s a major shift in how businesses communicate. ISDN and PSTN are old technology, and keeping them running is like maintaining an old gas-guzzling car when everyone else is switching to electric. As we get closer to 2027, legacy services will become more expensive and less supported. The smart move? Get ahead of the rush and switch to VoIP now.
What’s the Alternative? Enter VoIP & Microsoft Teams Phone
This is where we come in. VoIP (Voice over Internet Protocol) is the modern solution to business telephony.
Instead of relying on physical phone lines, VoIP uses your internet connection to make and receive calls. It’s flexible, cost-effective, and—most importantly—future-proof.
If your organisation is already heavily invested within Microsoft Teams, then Microsoft Teams Phone is a fantastic option. It lets you make and receive calls from any device, seamlessly integrating with your emails, calendars, and Microsoft Teams chats. Whether you’re in the office, at home, or on the move, you’ll always be connected.
