How we work

A clear route from requirement to rollout.

01

Tell us what is changing

Users, sites, existing contracts, pain points and must-have integrations.

02

See the right-sized architecture

We separate what you need now from features you can add later.

03

Agree the design before commitment

We confirm licences, handsets, connectivity, porting and implementation before anything is ordered.

04

Switch with a clear migration plan

Numbers, routing and users are tested before cutover, with a documented migration plan.

PSTN switch-off

The old UK phone network reaches its deadline on 31 Jan 2027.

If you still depend on PSTN, ISDN or related analogue services, the useful question is no longer “should we move?” It is “what should replace it, and what else relies on that line?”

Phones are only part of the audit. Check alarms, lifts, door entry, EPOS, fax and other analogue devices too.

Tell us what you need

What are you trying to fix?

Answer four short questions. The team can then respond with something specific rather than making you repeat the basics on a sales call.

Common questions

Before you switch.

Answers to the questions SMEs most often ask before changing phone systems.

Can we keep our existing business numbers?

Usually, yes. Number porting should be planned as part of the migration rather than treated as an afterthought.

Do we need to replace every desk phone?

Not always. Some deployments use desktop and mobile apps, some keep compatible IP handsets, and some need new devices. The right mix depends on roles and working patterns.

What should we audit before the PSTN switch-off?

Alongside voice lines, identify alarms, lifts, door entry, fax, payment terminals and other equipment that may still depend on analogue connectivity.
