No PBX hardware to buy and no big upfront cost — cloud phone systems that scale with your team. Because it’s cloud-delivered, we can activate your platform the same day — and a full switchover with number porting typically completes in 5–14 working days, so nothing goes live until your numbers are ready.
Cloud-delivered business voice — no PBX in your cupboard.
Hosted VoIP is the dominant model for UK business phone systems today. Your phone-system intelligence — call routing, voicemail, hunt groups, IVR menus, call recording, CRM integration, mobile and desktop apps — lives in the provider's data centre rather than as an on-premises PBX in your office cupboard. Handsets at your desks connect to it over the internet using standard SIP protocol. Incoming calls hit your business numbers via the carrier's network and arrive at your phones; outgoing calls route through the hosted platform to the public telephone network.
The operational difference vs an on-premises PBX: no capital investment in PBX hardware, no maintenance contract on ageing on-prem equipment, no need to scale hardware as headcount changes, no single-site failure mode, and natural alignment with hybrid working (the system doesn't care whether staff are in the office, home, or on a job — same desk phone, mobile app, or softphone behaviour everywhere). The operational difference vs ISDN or analogue copper PSTN: PSTN-switch-off ready, native integration with modern business apps, and significantly richer feature set without per-line hardware cost.
Because hosted VoIP runs entirely over your internet, the quality of the call depends on the quality of the underlying network. Telexico designs hosted VoIP deployments alongside the business internet and connectivity infrastructure they run on — full fibre or leased lines for primary connectivity, 4G/5G failover for resilience, QoS prioritisation engineered for voice. That's the difference between hosted VoIP that sounds professional and hosted VoIP that everyone complains about.
The UK telecoms moment.
Three things are driving every UK business onto hosted VoIP — and the timeline isn't optional. Hosted VoIP, hosted telephony and hosted PBX all describe the same thing: your phone system delivered from the cloud instead of a box in the cupboard.
Written and reviewed by Mickey Mall, Director, Telexico Communications Ltd — from hosted systems we install, port and support across the UK. Updated August 2026.
PSTN switch-off January 2027
BT is retiring ISDN and analogue copper PSTN. Many UK exchanges are switching off earlier. Every UK business on copper voice needs to migrate to all-IP delivery — hosted VoIP is the standard path. The longer you wait, the more rushed the eventual migration becomes.
Hybrid working is standard
Staff are in the office Monday, home Tuesday, on a job site Wednesday. On-premises PBX systems built for fixed-desk operations don't fit this reality. Hosted VoIP works wherever staff are — desk phone, laptop softphone, mobile app, all reaching the same numbers and using the same business identity.
AI Receptionist integration
The next wave of business voice is AI-powered call handling. AI Receptionist integrates natively with hosted VoIP — sits inside the platform, not bolted on. On-premises PBX systems struggle to integrate AI cleanly; hosted VoIP is built for it.
Per-user pricing scales naturally
10 staff, 25, 50, 200 — hosted VoIP pricing scales linearly with headcount. No PBX licence upgrades, no extra hardware shelves, no proportional maintenance cost. Add a user, add a per-user monthly cost.
Multi-site native
Multi-site businesses run one phone system across every location. Single dial plan, single feature configuration, unified analytics. On-prem PBX deployments needed separate hardware per site; hosted VoIP doesn't.
No PBX maintenance burden
The provider maintains the platform — patches, updates, capacity, redundancy, disaster recovery. You don't deal with PBX hardware failures, version upgrades, or out-of-warranty maintenance contracts. Operational risk shifts to the provider, which is where it belongs.

If you're still on ISDN or copper, here's the path.
BT switches off ISDN and analogue copper PSTN by January 2027. Many UK exchanges are switching off earlier. The migration from ISDN to hosted VoIP is well-rehearsed by this point — we've done it for hundreds of UK businesses across the West Midlands and beyond. The pattern works:
1. Free audit and design. We assess your current ISDN setup — how many channels, what call routing, what features you actually use vs what's just configured, what handsets you have, what's working and what isn't. The new hosted VoIP design replicates what works and improves what doesn't.
2. Provision the hosted platform. Set up call routing, hunt groups, IVR menus, voicemail, call recording (if applicable) in the new hosted environment. Configured but not live.
3. Number porting. Submit porting requests to move your existing business numbers from the old ISDN provider to the new hosted platform. Typically 5-10 working days. Old ISDN stays live throughout.
4. Parallel running. New hosted handsets arrive, get configured, tested alongside old ISDN. Staff trial the new system while old one is still primary. Issues identified and resolved before cutover.
5. Out-of-hours cutover. Scheduled cutover typically Saturday morning or evening. Calls flip from old to new at port-completion. Customer-visible disruption: minutes.
6. Post-cutover monitoring. First week is monitored closely — call quality, dropped-call rate, staff feedback. Tune any configuration. Old ISDN line decommissioned only after new is proven stable.
Operational realities that matter.
UK provider, UK platform
Telexico hosted VoIP runs on UK infrastructure with UK data residency, UK support, UK contractual relationship. Not a US SaaS with UK customers as an afterthought. Wolverhampton-headquartered (64 Chapel Ash, WV3 0TT).
Real engineer support
When you call support, you reach a UK engineer who can actually fix things — not a tier-1 call centre script. Response SLA backed by real engineering capacity. Named account management for ongoing customers.
AI Receptionist natively integrated
AI sits inside the hosted VoIP platform, not as a third-party bolt-on. Call routing seamless. Knowledge base configured once. AI handles overflow during peak hours and after-hours capture — typical missed-call rate drops from 20-30% to under 8%.
Bundle with the rest of your telecoms
Hosted VoIP plus business broadband plus business WiFi plus AI Receptionist plus 4G/5G failover plus CCTV — all on one Telexico relationship. Bundle economics typically 15-30% better than equivalent multi-provider stack.
Migration project-managed
Number porting, parallel running, cutover, decommissioning of old service — all project-managed end-to-end. Customer-visible disruption typically minutes. ISDN-to-VoIP migrations happen routinely without business impact.
Transparent pricing
What you sign for is what you pay, including renewal. No aggressive teaser pricing that resets 30-100% at year two. Per-user monthly cost is predictable across multi-year contracts.
Simpler telecoms. Fewer suppliers. Real support.

Why some VoIP sounds terrible — and ours doesn't
Every "VoIP is unreliable" story traces back to the same handful of engineering shortcuts — none of them inherent to VoIP. A call uses barely 0.1Mbps, so bandwidth is almost never the problem. What ruins calls is jitter (packets arriving unevenly — sounds like robotic warble), latency (delay — you talk over each other) and packet loss (gaps — words vanish). All three are fixable, and fixing them is the difference between a provider and a box-shifter:
| What we do | Why it matters to how calls sound |
|---|---|
| Pre-install line test | We measure jitter, latency and loss on your actual connection before you sign — and tell you straight if it needs sorting first. |
| Router QoS configured | Voice traffic gets priority over downloads on your network, so a big file transfer never crackles a customer call. |
| HD voice as standard | Modern wideband audio carries roughly twice the frequency range of an old landline — callers notice, even if they can't say why. |
| Wired-first handsets | Desk phones go on ethernet, not WiFi, wherever possible. WiFi calling works — but a cable never has a bad day. |
| UK voice infrastructure | Calls route through resilient UK data centres, not the cheapest international path — shorter paths, lower latency, no mystery hops. |
The honest caveat: if your broadband is genuinely poor, VoIP will expose it. That's why the line test comes first — and if the connection needs upgrading, we fix that as part of the same project (see business broadband) rather than installing phones onto a problem.
Number porting, without the fear
The question behind every switch: "will we lose our number?" No — UK number porting is a regulated, well-trodden process, and your existing number moves to the new system with customers noticing nothing. Here's how it actually runs. We submit the port with your authorisation and a recent bill; the losing provider validates it; a port date is agreed; and on the day, calls simply start arriving through the new system — typically with seconds of changeover, not hours. Single numbers usually port in about a week; multi-line and complex ports take two to four. Crucially, your old service keeps working until the moment of port, so there's no gap where callers hit a dead line.
Three things worth knowing. First, ports fail for boring admin reasons — a postcode mismatch with the losing provider's records is the classic — which is why we triple-check the paperwork before submitting. Second, don't cancel your old contract before the port completes: cancelling first can kill the number entirely. We sequence it so cancellation follows the successful port. Third, porting frees your number geographically — moving from Wolverhampton to Birmingham no longer means losing the 01902 number your customers know; it lives in the cloud and rings wherever you are.
VoIP security and the fraud nobody warns you about
Hosted VoIP done properly is more secure than the analogue lines it replaces — calls are encrypted in transit, and the platform sits in monitored UK data centres rather than an unlocked comms cupboard. But there's one VoIP-specific crime worth understanding: toll fraud. Criminals compromise weak phone systems — default passwords, exposed extensions — and pump thousands of pounds of premium-rate international calls through them overnight, usually discovered only when the bill lands. It's a genuinely large global industry, and unmanaged or badly configured systems are its feedstock.
Our platform is configured against it as standard: strong credentials enforced (no "1234" voicemail PINs), international and premium destinations barred unless you actually need them, calling patterns monitored with automatic alerts and cut-offs when something anomalous starts at 3am, and spending caps as a final backstop. It's the sort of protection you shouldn't have to ask for — so with us, you don't. If you're evaluating any VoIP provider, ask them precisely this question: "what happens if my system is compromised on a Saturday night?" The quality of the answer tells you everything.

Frequently asked questions
What is hosted VoIP?
Hosted VoIP is a business phone system where the phone-system infrastructure lives in the provider's data centre rather than on your premises. Your handsets connect to it over the internet. Calls route through the hosted platform — incoming calls hit your business numbers via the carrier's network and arrive at your handsets; outgoing calls go via the platform to the standard telephone network. Everything you'd associate with an on-premises PBX (call routing, voicemail, call recording, hunt groups, IVR menus, call analytics, mobile and desktop apps) is delivered through the hosted platform with no PBX hardware to maintain at your office.
How is hosted VoIP different from regular VoIP?
Regular VoIP is the technology — voice carried as data packets rather than as analogue signal. Hosted VoIP is the delivery model — your VoIP phone system is hosted by the provider rather than installed on-premises. The alternative would be on-premises VoIP (on-prem IP PBX hardware in your office, requires capital purchase plus maintenance) or, less commonly now, traditional ISDN/PSTN. Hosted is the dominant delivery model for UK business voice today because it eliminates on-premises hardware investment, simplifies multi-site deployments, and aligns naturally with the PSTN switch-off.
When is the UK PSTN switch-off and how does hosted VoIP fit?
BT is switching off ISDN and analogue copper PSTN by January 2027. Many UK exchanges are switching off earlier. Every UK business still on ISDN, analogue copper lines, or older hosted phone systems tied to the PSTN backbone needs to migrate to modern hosted VoIP (or alternative all-IP voice delivery). Hosted VoIP is the standard migration path because it requires no on-premises hardware investment, deploys quickly, and works over your existing business broadband or fibre connection.
How much does hosted VoIP cost in the UK?
Typical UK business hosted VoIP: £8-15/user/month for standard call packages, £15-25/user/month for advanced features (call recording, CRM integration, advanced reporting, AI receptionist add-on). Plus call charges (often unlimited UK calls included in higher tiers; international charged per-minute). Plus optional handset hardware (desk phones £80-200 each one-off, softphone apps included). Indicative monthly for a 10-person office: £100-300 all-in.
What's the minimum broadband speed needed for hosted VoIP?
VoIP needs roughly 100Kbps per simultaneous call. A 10-person office with all 10 on calls simultaneously needs ~1Mbps of upload bandwidth for voice (plus headroom for data). Most UK business FTTP delivers 50-200Mbps upload, comfortably handling voice plus normal data workloads. The bigger consideration is jitter and latency consistency — managed router with voice QoS handles this properly.
Will my existing business numbers transfer to hosted VoIP?
Yes — UK number porting is standard. Your existing landline numbers, 0800 numbers, and any other business numbers port across to the hosted platform during migration. The transfer is invisible to your customers — they dial the same number and reach you. Number porting typically takes 5-10 working days, during which your old phone system stays live.
How quickly can hosted VoIP go live?
Typical UK hosted VoIP deployment: 7-14 working days from order. Includes provisioning the platform, configuring call routing for your operation, number porting from existing provider, handset hardware delivery, on-site or remote staff training. Faster for simple single-site deployments; longer for complex multi-site or CRM-integrated rollouts. Old phone system stays live throughout — cutover scheduled for after-hours so day operations aren't disrupted.
How long does it take to port my number to hosted VoIP?
Single numbers typically port in around a week; multi-line or complex ports take two to four weeks. Your existing service keeps working right up to the moment of port, so callers never hit a dead line — and we sequence any old-contract cancellation to happen only after the port completes.
What happens to my calls in a power cut or internet outage?
The phone system itself lives in the cloud, so it stays up even when your office doesn't. Calls automatically divert to mobiles or the app, and voicemail-to-email keeps capturing messages. Add 4G/5G failover and even your office connection rides through the outage.
Can I keep my existing desk phones?
Usually, yes — modern IP handsets from the major brands typically reprovision onto our platform. Older analogue phones can often be adapted with a small gateway, or replaced affordably. We audit what you have before quoting, so nothing is bought unnecessarily.
Is hosted VoIP secure?
Yes, when configured properly — calls are encrypted in transit, the platform runs in monitored UK data centres, and we lock systems against toll fraud as standard: strong credentials, barred premium destinations unless needed, anomaly monitoring and spending caps. It's considerably more secure than the analogue lines it replaces.
Do I need special broadband for hosted VoIP?
No — a single call uses roughly 0.1Mbps, so any healthy business connection carries plenty of simultaneous calls. What matters is stability, which is why we test your line for jitter, latency and packet loss before installation and configure router QoS so voice always gets priority.
Can staff make business calls from their personal mobiles?
Yes — the mobile app presents your business number on outbound calls and rings for inbound ones, keeping personal numbers completely private. When someone leaves, you reassign their extension and the business number stays with the business.
What's the difference between hosted VoIP and Microsoft Teams Phone?
Teams Phone adds calling to Microsoft Teams — great if your business lives in Teams all day. Hosted VoIP is a dedicated phone platform with deeper call handling: queues, wallboards, reception consoles, call recording. Many businesses run both, integrated. See our Teams Phone vs VoIP comparison for the full breakdown.
Is there a minimum number of users or contract length?
No meaningful minimum — we look after one-person businesses and hundred-seat offices on the same platform. Contracts are kept clear and fair; we'd rather keep you by being good than by small print.
Can hosted VoIP record calls?
Yes — call recording is available per user or per team, with secure storage and simple retrieval. If you take card payments or operate under FCA rules we'll configure recording to meet your compliance needs, including pause-and-resume for payment details.
