The Big Switch Off

Are you ready for the Big Switch Off?

Traditional landlines are heading to the cloud.

Vivio are here to guide, support and partner with you to develop and implement your Big Switch Off strategy and keep you connected…

Our team of business communication experts are on hand to manage your digital transformation strategy and help you to prepare for the 2025 ISDN and PSTN switch off.

It’s time to take advantage…

The PSTN (Public Switch Telephone Network) has been the UK’s primary communication and connectivity network for decades, with some of the copper cables having been laid in the 19th century. It’s time to move to the 21st century and beyond, which is why Openreach are switching off the PSTN service in 2025 and embracing a fully digital future.

With the deadline fast approaching, now is the time to take advantage of the benefits of moving to a cloud telephony solution.

We understand that every business is unique, which is why we work with all the leading cloud telephony suppliers to tailor a solution which works for you, our Client.

Our proactive, partner-led approach will ensure a full audit of your business communication and connectivity, offering continued support and guidance on achieving full digital transformation.
