Hosted VoIP for UK business.Cloud-delivered. No PBX. PSTN-ready.
Your phone system, hosted by Telexico — no on-premises hardware to buy, configure or maintain. Works over your business broadband. Ready for the January 2027 PSTN switch-off. UK installed and supported.
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.
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.

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.
