Can we keep our existing telephone numbers?

Yes. Numbers can be ported from any UK provider. We manage the process end to end and coordinate porting on a scheduled date.

What happens to VoIP phones when the internet goes down?

Calls automatically fail over to mobiles or an alternative number based on a plan we agree with you. On resilient connectivity, this rarely happens — but we plan for it anyway.

Are you tied to one manufacturer?

No. We support the leading UK-hosted platforms and can advise objectively based on how your business actually uses telephones.

Can we integrate calls with our CRM?

Yes. Common integrations include Salesforce, HubSpot, Microsoft Dynamics, and recruitment CRMs. We also build bespoke integrations where useful.

Sound familiar?

The problems this fixes.

If two or more of these are hitting your business, this is the right conversation to have.

Missed calls because the current system is unreliable or badly configured.

Staff working across multiple offices, home and mobile without a single number plan.

A phone contract that renewed automatically and now costs more than it should.

Old handsets that will stop working when the PSTN switch-off completes.

A provider that takes days to make a simple change.

What changes for you

Concrete outcomes, not marketing language.

Every benefit below is something we can point at within the first month.

One number plan

Route calls across offices, home working and mobiles without confusion.

Ready for the PSTN switch-off

All-IP calling on connectivity we understand and can support.

Fast changes

Menus, hunt groups and out-of-hours schedules updated by real engineers, not tickets in a queue.

Call intelligence built in

Optional Atom Insight adds recording, transcripts, summaries and coaching.

The full picture

The detail behind the headline.

If you like to read the small print before you talk to us — this is for you.

A modern cloud phone system, without the tie-in you regret

Atom Voice is a full unified-communications platform designed for UK businesses that are tired of PBX cupboards, dropped calls and providers who take three days to move an extension. It runs on carrier-grade infrastructure hosted in UK data centres, with geo-redundant call routing and encrypted signalling across every device.

You get a real phone system — deskphones, softphones, mobile apps, Microsoft Teams calling, contact-centre queues and analytics — configured by engineers who know how it fits together. Not a marketplace login and a PDF.

One number plan across every device your team uses

The people you employ answer calls in more places than a single deskphone. Atom Voice unifies mobile, desktop, deskphone and browser under a single UK number per user, with intelligent presence, twinning, follow-me routing and call handoff mid-conversation.

Assign one direct-dial number to a user and let them decide, per hour of the day, where it rings. Or push the whole team into an intelligent queue with skills routing and callback. Or route to your Microsoft Teams tenant with native Teams calling. Same platform, same admin portal, same bill.

Ready for the PSTN and ISDN switch-off

Openreach are removing the analogue and ISDN copper network by the end of January 2027. Every UK business phone line will be delivered over IP by then. Atom Voice is an all-IP platform from the ground up: nothing on your premises is dependent on copper, and no critical service — payment terminals, lift lines, alarm autodiallers — is left behind, because we survey and migrate those alongside the phones.

If your current provider has not written to you about the switch-off, that is a warning sign in itself.

Changes made in minutes by named engineers

Every Atom Voice customer has a named account engineer with a direct number. Menu changes, out-of-hours schedules, new users, hunt-group re-ordering and voicemail-box tweaks are typically live within the working day, not the working week. Emergency routing changes — an office evacuation, a snow closure, a burst pipe — can be applied in minutes from any device.

Built to work with Atom Insight and the rest of your stack

Every call that lands or leaves your business can be recorded, encrypted at rest, transcribed and summarised. Atom Insight lifts those transcripts into structured coaching, customer summaries and CRM notes automatically. Every call your team makes contributes to a growing, searchable record of your customer relationships — not just a bill.

Atom vs. the alternative

The differences you'll feel.

Same technology on paper. Very different experience in practice.

How Atom is different

Typical reseller

Atom IP

Ownership of the outcome

Typical:Reseller of a reseller — nobody responsible when it breaks

Atom:One team, from network to handset, accountable end to end

Change turnaround

Typical:3–5 working days via ticket queue

Atom:Same-day for standard changes; emergency in minutes

Handset lock-in

Typical:Proprietary handsets locked to their platform

Atom:Open-standard SIP handsets you keep if you leave

Contract clarity

Typical:Service and hardware finance bundled together

Atom:Service and hardware invoiced separately, terminable independently

Call intelligence

Typical:Add-on from a third party if available at all

Atom:Atom Insight built in, on the same platform

PSTN switch-off readiness

Typical:Vague reassurance, no migration plan

Atom:Written migration plan for every service before it's needed

Same platforms. Very different experience in practice.Atom IP advantage

How switching works

From first call to steady state.

A typical engagement runs to about four weeks. Nothing dramatic happens without your sign-off.

1
Discovery (Week 1)
We audit your current bill, contract, call flows and pain points. Nothing is quoted until we understand what you actually need.
2
Design (Week 2)
We map extensions, routing, integrations and hardware. You review a written plan before we build anything.
3
Build (Week 3)
The platform is configured, integrations are tested, deskphones are provisioned and shipped. We port numbers on an agreed date and time.
4
Cutover (Week 4)
A supervised go-live outside business hours. Engineers on-site or on-call. Old system stays live until cutover completes.
5
Steady state (Week 5+)
A named engineer for the whole engagement. Quarterly reviews to keep the platform aligned to how you actually work.

“Good guys — worked with them to switch over from a previous very good supplier. They have gone above and beyond to understand our needs and bespoke systems to help support our specific needs. Transition over on getting their systems up and running was smooth. As a small business owner, trust and confidence are important to me.”

“We have been using Josh at Atom for a few years now. Service has always been amazing. Just today our router blew up due to a power surge and he came out promptly with a new one to make sure we were back online in time for trading. Would highly recommend.”

“There aren’t many telecom providers that can be described as truly honest and straightforward. Georgia was very well spoken and made me feel my company was in the right hands. Ollie and Josh responded promptly throughout getting my phones and security systems set up. The install was seamless with no drop in connectivity and no technical issues since.”
