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

Common signs we hear at almost every audit.

  • You're still on BT landlines or ISDN. January 2027 deadline →
  • You're locked into a hosted UC contract you can't read.
  • You inherited a PBX and nobody's quite sure how it works.
  • Your operations manager is also your accidental telecoms admin.
  • The phones break and someone's day disappears.

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.

The work that disappears from your desk.

Six things we do for every customer.

01

Set up and licence 3CX (PRO tier)

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

02

Supply and install handsets

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

03

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.

04

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.

05

Monitor and maintain

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

06

Answer the phone when something needs fixing

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

Service standards.

More on our service

Less than half what the big SaaS phone platforms charge.

Managed 3CX puts the real cost stack on the page. The big SaaS phone platforms (RingCentral, 8x8, Aircall) bundle features into £20–30/user tiers; we run the same feature set for £6–10 and break out every line at audit.

Port Phones
£6–10 per user/month
Includes call recording, queues, CRM, mobile and softphone apps. Setup and handsets quoted separately.
RingCentral, 8x8, Aircall
£20–30 per user/month
Mid-tier plans with the same feature set on each provider's UK pricing pages.

Why Port Phones?

We work with UK SMEs that need a working phone system and don't want to think about how it runs. 10 to 80 users is our sweet spot. Fixed office, inbound calls matter, no in-house telecoms specialist.

Port Phones exists because UK SMEs get sold opaque per-user contracts, two-year handcuffs, and 'cloud hosting' line items that are really £69/month self-service products. The phones are fine. The relationship around them is broken. We run 3CX exclusively, transparently, on month-to-month after the first year.

vs. big providers

No two-year lock-ins

12-month initial term, then month-to-month. Leave whenever you want. We'll even port your numbers out if you do.

vs. DIY

We handle everything

You don't need to learn VoIP. We set it up, run it, maintain it, fix problems. You handle the actual phone calls.

vs. hidden fees

Transparent pricing

We quote at the audit. Full breakdown of where every £ goes. No surprise charges for config changes.

Common questions.

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

Two bases: head office at 31-33 Commercial Road, Poole, Dorset, and a London base at Canary Wharf. We work nationally — modern VoIP doesn't care where your handsets sit.
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.
Yes. UK-incorporated businesses on UK numbers. We're not set up for cross-border carrier work or non-UK numbering plans.
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 audit tells us in 30 minutes whether we're a fit.
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.
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 audit — see the switch-off guide for the deadlines.
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.
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.
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.
After the initial 12-month term, you can cancel with 30 days notice. No penalties, no questions. We'll port your numbers to your next provider at no charge. We keep customers by being good, not by trapping them in contracts.
