Frequently asked questions
What is a digital telephone system?
It's an all-IP phone system that carries calls over the internet instead of the old analogue or ISDN phone lines, usually hosted in the cloud.
Is a digital telephone system the same as VoIP?
In practice, yes — 'digital telephone system', 'VoIP' and 'cloud phone system' all describe calls carried over the internet rather than copper lines.
Do I need to switch before the PSTN switch-off?
Yes — analogue and ISDN lines are being retired before 2027, so moving to a digital system ahead of time avoids a rushed migration.
Will I keep my existing numbers?
Yes — number porting is included, with a switchover planned to minimise disruption.
Do you provide the internet it runs on?
Yes — we can supply the broadband, full fibre and 4G/5G failover your digital phone system needs, all under one relationship.
