UK business phone system

Keep an eye on every call.

NMPBX is a complete cloud VoIP phone system for UK business. Calls, handsets and support are all included, and every conversation is scored for tone and outcome the moment it ends, so you can see what's working and stop losing business to calls that slip through the cracks.

3-month satisfaction guarantee Won't be beaten on price UK-hosted, UK-supported

The UK phone network switches off on 31 January 2027. Every business still on analogue or ISDN lines has to move before then, and porting numbers takes longer the closer we get. We handle the whole migration for you.

What this means for you
Watch the overview

See NMPBX in action.

A quick look at how NMPBX works for real businesses: how calls reach your team, what the AI picks up on every conversation, and the dashboards you'll use day to day.

  • Calls answered on desk phones, laptops and mobiles, all on one system
  • Every call transcribed and summarised automatically
  • Live dashboards showing answered, slow and missed calls
The whole feature list

Every call,
decoded.

Every feature below is included on both plans, Pay As You Call and Unlimited alike. The only difference between them is how you pay for your calls.

● AIIncluded on all plans

AI sentiment analysis.

Every conversation is scored as soon as the call ends. NMPBX listens for tone, pace, keywords and silence, then surfaces the calls that need a human looking at them. No more "tell me how the call went" guesswork.

  • See every call, not just a sample. Each inbound and outbound call is scored the moment it ends, so you judge performance on the full picture rather than the handful someone had time to listen back to.
  • Act on important calls instantly. Get an immediate email alert when a call contains the keywords, tones or long silences you care about, so problems and opportunities are dealt with the same day rather than a month later.
  • Report the way your business actually works. Build dashboards by team, site or individual, so the numbers land with the people who need to act on them.
  • Prove your coaching is working. Track sentiment across weeks and months and see in the data whether last month's training actually changed how your team handles calls.
  • No call slips through the net. Analysis runs whatever the duration, so a twenty-second brush-off gets the same scrutiny as a forty-minute negotiation.
● AIIncluded on all plans

Search by meaning.

Every call is transcribed, then made searchable by meaning, not just keywords. Type something like "customer querying their bill" and NMPBX finds those calls even when nobody used those exact words. Each result comes with its sentiment score and the outcome, so you can see which conversations helped the business and which quietly cost it.

  • Search in plain language and find calls by what they were actually about, even when those exact words were never spoken.
  • Every result shows its sentiment score and the business outcome, so you can see how a call affected the business and why.
  • Set up alerts for the things you want to keep an eye on. NMPBX watches in the background and surfaces only the calls that match.

Integrates with your CRM.

If you have the NMPBX app on your device, you can click or tap a phone number and we'll dial it for you. That works across your web browser, including on this site, and in well-built software like Outlook, where clicking someone's number opens NMPBX to place the call.

  • CRM connection available through an optional add-on for Salesforce, Zoho, SugarCRM, SuiteCRM, ConnectWise and Zapier.

🔒All plans

Security, included as standard.

Everything below is in place out of the box, not on a higher tier, not behind a sales conversation.

  • Role-based access control, audit logs, granular permissions for recordings and transcripts.
  • Full DPA, ICO-registered, GDPR-aligned. Cyber Essentials Plus certified.
●All plans

UK support, run by people who answer.

Our support team is in Wymondham, Norfolk, and our engineers travel out to customers across the UK when an on-site visit is needed. You call one number and reach a skilled engineer, not a phone menu or a call-centre script.

  • UK office hours support included on every plan.
  • You speak directly to a skilled engineer, and the person who answers is usually the one who resolves your issue.
  • Dedicated account manager from day one. Quarterly health-checks built into the contract.
  • Strict, contractual SLAs covering response and resolution times, so you always know what to expect.
  • Free training for your team: onboarding, refreshers, new-feature walkthroughs.
◧Optional add-on

See your phone system in real time.

NMPBX Wallboard gives your team a live, customisable view of what's happening across your phone system, so nobody has to guess how busy the lines are or whether calls are going unanswered.

  • Spot a queue before it becomes a complaint. Calls waiting, answered and missed are all on screen as they happen, so your team can react while the caller is still on the line rather than finding out afterwards.
  • See how each agent is performing. A live leaderboard shows inbound calls, answered calls and talk time per extension, which is exactly what a sales floor wants on the wall.
  • Show only what matters to you. The board is customisable, so you choose the figures your business actually runs on instead of working around a fixed layout.
  • Put it where the team can see it. Display it on a large screen in the office, or keep it open on a computer if people work remotely.
  • Available as an optional extra. Wallboard can be added to either plan whenever you need it, and we will set it up for you.

Common questions

Your questions,
answered.

If your question isn't covered here, contact us and we'll answer it directly, usually in a short call rather than pages of paperwork.

Ask us anything
How can NMPBX be £2.95 per user, per month?
We own and operate the underlying platform and sell direct, with no resellers taking a cut. On Unlimited you simply pay the per-user cost with your UK calls included; on Pay As You Call you pay the user licence plus the calls you actually make. Every feature, including the AI, comes with both plans. The only difference is how you pay for calls. We're not loss-leading, we're just cheaper.
What does the 2027 PSTN switch-off mean for my business?
On 31 January 2027 the UK's copper phone network is switched off for good, so any analogue line or ISDN circuit stops working. It affects more than desk phones: broadband over copper, alarms, lifts, door entry and card terminals can all rely on those lines. Moving to a cloud system sorts it, and we handle the audit, the migration and the number porting for you. The sooner you start the easier porting is, so it is worth doing on your timetable rather than in the final months. Read our full switch-off guide.
Will I have to change my phone numbers?
No. We port every number across as part of the switch. Geographic, non-geographic, freephone, international, all handled. You keep what you have.
Can I keep my existing handsets?
In most cases, yes. Most modern SIP-compatible handsets will work, though we'll always check yours to be sure. If your kit is particularly old, new handsets are available as a hardware add-on at £1 per user, per month. We don't push handset rental for the sake of it.
What happens if I'm mid-contract with another provider?
Send us the contract. We'll read the exit clauses, work out the genuine cost of leaving, and give you a clear picture of whether and when it makes sense to move. Plenty of our customers came across mid-contract.
Is the AI doing anything weird with my call data?
No. Audio is processed in UK data centres, transcripts and sentiment scores belong to you, and nothing is used to train third-party models. Full DPA available before signature.
Do you only work with East Anglia businesses?
That's our backyard, but no, we work with businesses of all sizes right across the UK. Our support team is UK-based and we can deploy nationally, with on-site visits included where they're needed.
What if I'm not happy after switching?
Every contract comes with a three-month satisfaction guarantee from day one. If we don't deliver what we promised in those first three months, you can leave with your numbers and we won't argue about an early-termination fee. To date, not a single customer has ever needed to.
