Port Phones: UK 3CX Managed Service Provider for SMEs

What the current setup is actually costing you.

Three costs that don't show up on the invoice.

It never quite goes away.

Resetting extensions, onboarding new starters, troubleshooting call quality, chasing your provider's portal. The jobs are small. The interruptions aren't.

Opportunity cost.

You were hired (or hired yourself) to do something else. Every hour you spend on the phone system is an hour you're not doing it.

When it breaks, you're on your own with it.

On a DIY 3CX or a hosted UC support queue, an outage starts with you working out who to ring. Inbound calls don't pause while you do.

What it looks like when someone else runs it.

Four things that change the day someone else picks it up.

One bill. 3CX licence, hosting, SIP trunks, monitoring, support — all on it.
One number to call. A senior engineer, not a ticket queue.
Day-to-day changes handled. New starters, call-flow tweaks, updates, all part of the service.
No telecoms learning curve. We run it, you use it.

The work that disappears from your desk.

Six things we do for every customer.

Set up and licence 3CX (PRO tier)

Extensions, ring groups, IVR, call routing, voicemail, business hours — configured to your office.

Supply and install handsets

Yealink IP phones at trade prices, installed on-site, every extension provisioned. You walk in on day one and dial.

Port your existing numbers

Moved from BT (or whoever you're with) to your new SIP trunk. Same number, no downtime if we can help it.

Train your team

An hour each with reception and key staff. Transfer calls, retrieve voicemail, use the mobile app, manage call flow when someone's off.

Monitor and maintain

We watch the system 24/7. SIP outage, recording failure, config drift — usually caught and fixed before you notice.

Answer the phone when something needs fixing

One number. A senior engineer picks up. No ticket queue.

Service standards.

Response time. Call quality. Data residency.

Support

24/7

Senior engineer picks up the phone. No ticket queue, no escalation.

Product

SUB‑15ms

UK-hosted 3CX to UK Gamma SIP over a UK ISP. Measured, not marketed.

Data

100% UK

London data centre, Gamma UK SIP. No cross-border transfer.

Priced from a scoping call, not a plan tier.

The big SaaS phone platforms sell you a per-seat tier and let you work out which features you are paying for. We size the system to how many calls you actually make at once, then quote it. Your price depends on your concurrency, how many numbers you keep, and whether you want handsets, so we work it out with you rather than guessing on a pricing page.

A scoping call takes about twenty minutes and costs nothing. You get a written quote with every line spelled out and no obligation.

Why Port Phones?

We work with UK SMEs that need a working phone system and don't want to think about how it runs.

Running a phone system well is mostly the unglamorous parts: the setup, the number porting, the handsets, and looking after it. We run 3CX for UK businesses, priced simply, and answer the phone when you need us.

Common questions.

Switch-off specifics live on the PSTN switch-off guide.

Where are you based?

Head office at 31-33 Commercial Road, Poole, Dorset. Engineers work from both Poole and Canary Wharf, London. We work nationally — modern VoIP doesn't care where your handsets sit.

Do you cover London?

Yes. Same service, same pricing, same person answering the phone. London businesses are a meaningful part of our prospect base — see our VoIP London page for the geo specifics.

Do you only work with UK companies?

Yes. UK-incorporated businesses on UK numbers. We're not set up for cross-border carrier work or non-UK numbering plans.

Do you work with industries other than the ones you list?

Yes. Our sector pages (law firms, dental and medical practices, estate agents) are where we've documented the deepest workflow detail, but any UK SME running roughly 10 to 80 users is in scope. The scoping call tells us in 30 minutes whether we're a fit.

What's included in the monthly fee?

Your 3CX licence, hosting, SIP trunks, system monitoring, ongoing support, and any config changes you ask for. Setup, handsets, and number porting are quoted as a one-off at the start. Handsets are charged at trade-plus, not marked up to incumbent rates.

Is everything cloud-hosted? What about my on-premise PBX?

3CX is cloud-first and that's how most customers run it, but it also runs on-premise if you have a hard requirement. Either way, the PSTN switch-off in January 2027 means any legacy PBX needs a SIP front-end at minimum. We scope this during the scoping call — see the switch-off guide for the deadlines.

Do you sell mobile phones, SIM cards, or connectivity?

No. We're 3CX-only specialists, not a multi-product reseller. If you need broadband, mobile, leased lines, or CCTV, your IT MSP or a connectivity-focused provider will serve you better. We'd rather do one thing properly than four things adequately.

What happens if something goes wrong?

Hosted infrastructure is monitored 24/7 and most issues are caught before customers notice. P1 incidents (phones down, or audio quality affecting business operations): 12-minute median first response, 30-minute outer bound, 24/7 including weekends and bank holidays. Degraded-but-workable issues: same business day. Config changes and questions: next business day. Hosted infrastructure runs to a 99.95% uptime target. Full SLA.

Do you work with my existing IT provider?

Yes. Many of our prospects come from local IT MSPs who handle Microsoft 365, laptops, and networking but don't do voice. We work alongside them, refer back, and run a small referral programme for IT MSPs who want to bring us in for their customers.

How long is the contract, and how do I leave?

You commit to an initial term, typically two to three years, then it rolls yearly with 90 days' notice before each renewal. Your price is held within each term, and if we ever raise your tier by more than 15% you can leave penalty-free. Early exit covers our lost margin, not the full fee, and we port your numbers out at no charge. It's all in the agreement, in plain English, with no hidden auto-renewals.

Who looks after you and your phone system?

You're probably here because one of these is true.
