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.
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.

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.

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.

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.
Work out your price in seconds
See what you'd pay, before you speak to anyone.
Type in your team size and our calculator shows your monthly cost, your per-user rate and your monthly cost. No form, no sales call, no waiting for a quote.
Choose whichever suits you: phone, email, a full audit of your current bills, or a meeting at one of our offices. We respond to every new enquiry and quote request within one working day. Once you're with us, our UK support team replies within fifteen minutes during office hours.
We'll come back with a like-for-like figure and the saving, written down. If you've got recent bills, send them, that's where the honest comparison happens.
Norfolk-built, UK-focused
Twenty years of telecoms experience. Built into one simple product.
NMPBX is the telecoms product we kept wishing existed when we were helping customers escape contracts with everyone else. So we built it. Fair pricing, real engineers, AI that actually helps, for UK businesses of every size.
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.
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.
NMPBX is a product of Netmatters Ltd, a Norfolk-based IT, software and digital services group that's worked with UK businesses of all sizes since the mid-2000s. The same business that builds your phone system can also handle your website, your IT support and your cyber security if you want it. None of it is mandatory.
