Port Phones doesn't compete with the customer doing it themselves. We compete with the customer's willingness to switch from whatever broken legacy phone system they have today.
The 5% who'd seriously DIY are filtered out at audit. For the other 95%, DIY never enters the consideration set.
Our typical buyer is filtered by an upper threshold — “has someone in-house or via MSP who handles voice”. The audit excludes the small cohort who would seriously consider DIY before we ever meet them.
For the remaining 95%, DIY is a theoretical option that never enters the consideration set. Here's why, ranked roughly by how much each reason matters.
Ranked from biggest structural lever to smallest.
A professional services firm whose principals bill £150–300 per hour cannot economically spend 40–80 hours setting up a PBX. The “saving” of ~£3,000 over 24 months costs them £8,000–16,000 of partner opportunity cost. This reason does not weaken with time, technology improvement, or 3CX product simplification.
If phones break during a peak period — tax season for accountants, lambing for vets, exchange days for estate agents — the firm bleeds revenue and client trust. The managed provider is bought as insurance: 24/7 monitoring, single throat to choke, out-of-hours support. Not as telephony.
Most SME owners do not know 3CX is fundamentally free at small scale, that SIP can be bought direct from Gamma at ~£4 per channel, that handsets are available at trade prices, that porting is procedural not magical. They cannot DIY what they do not know is DIY-able. Managed providers benefit from this opacity and have no incentive to reduce it. We publish a line-by-line cost decomposition on our pricing page precisely because most don't.
A 35-person accountancy billing £4–6M per year does not optimise for a £900-per-year telephony differential. Willingness to pay is a function of the size of the problem, not the cost of the input. Partners would rather pay £900 to never think about phones.
SMEs want one vendor, one bill, one outcome. The cognitive load of assembling licence + hosting + SIP + handsets + install + porting + support is itself a deterrent — independent of cost. Even procurement teams who could project-manage the assembly typically choose not to.
AML record-keeping, GDPR on recordings, business-continuity expectations from clients. “We run our own phones from a cupboard” reads poorly in due diligence; pointing at a 3CX Titanium Partner reads well. The managed-service relationship is partly a documentation artefact for the customer's own auditors.
DIY converts a clean opex line into chunky internal labour plus procurement work that nobody wants to own. CFOs prefer predictable opex. The managed-service monthly fee is friction-free on a P&L; the DIY equivalent is “why did we spend 80 partner hours on phones last quarter?”
SME deals come via referrals: accountant networks, MSP recommendations, chamber of commerce, professional services peers. The £/month figure is partly buying “I trust this person to pick up the phone when something breaks.” You can't buy that on 3cx.com.
Bundling “Cloud Hosting” as a line item on a quote makes it sound like specialist infrastructure. Most buyers don't realise 3CX-hosted is a £69-per-month self-service product on 3cx.com. The bundling is the moat.
You compare a managed-3CX quote (£7–10 per user per month) to RingCentral, 8x8, or Aircall at £20–30 per user per month and conclude managed-3CX is good value. DIY-3CX never enters your comparison set. It might as well not exist on your market map.
Three operational implications from the ten reasons above.
It isn't. The realistic floor is what you'd find acceptable per user per month against the alternatives you actually compare against — RingCentral and 8x8 at the high end, T2K-shape managed providers in the middle. We sit comfortably at £6–10 per user per month and stay well below both.
Publishing “here is exactly what 3CX costs direct, here is what we add, here is why most firms still pick a managed provider” turns the opacity moat in reason 3 into a trust moat incumbents can't replicate without giving up margin. Structural advantage, not a price war.
The buying trigger is rarely “we found a cheaper provider”. It is usually a PSTN switch-off letter, a 3CX renewal price-rise letter, an office move, a telecoms hire, a compliance audit, or the existing system breaking. Outreach matches those events — not framed as a price-shopping pitch.
Boring ones. AI and bleeding-edge integrations are not the wedge.
That's what we sell. If the rest of this site sounds plain, that's why.
Reason 2 above is the operational-risk argument. That logic only holds if “support” is a defined commitment, not a vibe. Here's what is committed to in writing on every contract.
12-minute median first response, 30-minute outer bound, 24/7 including weekends and bank holidays. P1 routes to a senior engineer with direct platform access. Hosted infrastructure runs to a 99.95% uptime target.
One extension misbehaving, recording gap, voicemail not delivering to email. Same business day, Mon–Fri 09:00–18:00.
Next business day. Includes dial-plan tweaks, IVR edits, hold-music swaps, anything that isn't time-critical.
P1 is graded from the customer's seat. “Phones down” means inbound or outbound calling is broken for the firm, not just one user. The definition is not argued during an incident. When evaluating any UK 3CX partner at audit time, the question to ask is: “What's your median first-response time on a P1 ticket, and what counts as P1?”

If you're already with a managed-3CX provider and the bill feels high, bring us your current invoice at the audit. We'll walk you through which line items match the real cost stack and which ones are markup. No pressure to switch — sometimes the right answer is “your current provider is fine, here's why.”
