How it works

Here's how switching works.

Switching is simpler than staying put. Three steps, and we handle the heavy lifting.

1

Submit your enquiry

We'll get a good understanding of your setup and offer a solution that adds value.

2

We set everything up

We get everything ready and port your numbers across. You carry on as normal.

3

Full visibility from day one

Your team gets full call visibility from day one. No training course required.

The whole feature list

Every call,
decoded.

A proper run-through of what comes with NMPBX. Everything below is included on both plans, Pay As You Call and Unlimited alike. The only difference between them is how you pay for 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.

  • Scored automatically after every inbound and outbound call, with no minimum duration.
  • Set the tone, keyword and silence triggers that matter to you, and get an email alert as soon as a call matches.
  • Multiple dashboards for advanced call reporting, so you can view your data however your business is structured.
  • Tracks improvement over time, so you can see whether last month's coaching actually landed.
  • Works on calls of any length, with no limit on the analysis.
● 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.

Plays nicely with your stack.

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.

  • Click-to-call from your browser and from well-built software like Outlook, straight through the NMPBX app.
  • CRM connection available through an optional add-on for Salesforce, Zoho, SugarCRM, SuiteCRM, ConnectWise and Zapier.

🔒All plans

Boring, solid security.

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

  • UK-hosted infrastructure. Your audio stays in the UK, and if you use the AI features we process them in the EU, keeping everything inside UK and EU data protection rules.
  • 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.

Customer stories

Real businesses, real results.

These are real UK businesses that made the switch to NMPBX. Here is what changed for them, in their own words: clearer calls, fairer bills, and visibility they never used to have.

● Featured Self storage North Pickenham, Norfolk

How a growing Norfolk self-storage business took every call on the move, and stopped letting enquiries slip.

North Pickenham Storage runs a 10-acre self-storage site in Norfolk, serving private and commercial customers seven days a week. With no way to take calls away from the office and no visibility into missed enquiries, business was being lost without anyone knowing why. We moved them to NMPBX: full mobile calling with the office number shown on outbound calls, plus AI sentiment analysis and call reporting that finally showed them what was happening on every call.

✓ Calls made & taken anywhere
✓ Office number on outbound calls
✓ AI sentiment on every call
✓ Missed calls now visible

The sentiment analysis and call reporting tools have been particularly valuable.

Words from real customers

Why businesses switch and stay.

Some come for the saving. Some come because they were tired of poor service and wanted a provider that actually delivers. Most stay because the dashboard tells them things they never used to know.

"

Since implementing the NMPBX phone system, we have seen significant improvements in the way our team communicates internally and with customers. The platform has provided us with greater flexibility, improved visibility across customer interactions, and valuable operational insights that have helped improve both productivity and customer experience. The sentiment analysis and call reporting tools have been particularly valuable. These features have given us far greater visibility into customer interactions and team performance. We are now able to identify trends in customer service conversations, monitor response quality, and spot opportunities where calls may not have been handled as effectively as possible. The reporting tools have also highlighted missed calls and potential missed sales opportunities that previously may have gone unnoticed.

Common questions

Answers,
without the waffle.

Can't see what you're after? Drop us a line. We'd rather answer it in a quick five-minute call than send over pages of paperwork.

Ask us anything
How can NMPBX be £1.05 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.
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.
