The Big Switch Off

Businesses need to make sure they move to the cloud as soon as possible with the legacy telephone network due to be completely switched off by 2025. In understanding the way your business operates we can recommend a solution to suit you now that’s also scalable for the future.

PSTN - the Public Switched Telephone Network is a network of underground copper wired hardwired from homes and business to switching centres. This carries voice calls through the network to the call receiver’s telephone. The advancement of the internet over the last century means user requirement has evolved rapidly and The Big Switch Off allows for new technology and infrastructure to be developed.
