UK business phone systems in 2026.
Different operations need different systems. Here's the honest landscape and where each genuinely fits.
Cloud-based VoIP (hosted PBX)
Everything in the cloud. No on-site hardware. Scales by user count. Standard option for UK SMEs in 2026 — best blend of features, cost and management simplicity.
Best for: single-site or multi-site UK SMEs, 5-500 users, anyone wanting modern features without server-room overhead.
VoIP technical detail →Microsoft Teams Phone
Your business phone system runs inside Microsoft Teams. Calls from the Teams app, voicemail in Teams, call recording in Teams. Direct Routing or Operator Connect deployment.
Best for: businesses already heavily on Microsoft 365 / Teams, where unified Teams + voice is operationally clearer than running two separate systems.
Teams Phone setup →SIP Trunks (keep your existing PBX)
You already have a phone system (possibly an old on-premise PBX or hybrid setup). SIP trunks replace the old ISDN/PSTN line connecting it to the outside world. Cheaper than full replacement.
Best for: businesses with substantial investment in existing PBX hardware that still works fine — just need to modernise the line.
SIP Trunks detail →AI-powered phone systems
Your phone system + AI Receptionist handling routine calls, answering FAQs, booking appointments, qualifying leads, escalating to humans. 24/7 coverage including lunch breaks, evenings, weekends.
Best for: any UK SME currently missing 20%+ of inbound calls. AI typically pays back in 2-4 weeks for service businesses.
AI Receptionist →Multi-site phone systems
Same phone system across 3+ sites. Internal extension dialling between sites. Unified call reporting. Failover between sites if one goes down. Central admin.
Best for: UK businesses operating across multiple locations — retail chains, multi-branch professional services, hotel groups, multi-site healthcare.
Multi-site connectivity →Hybrid systems (transitional)
Cloud-based system running alongside existing on-premise hardware during a transition period. Useful when migration needs to happen in stages — typically 6-18 month migration plans.
Best for: larger UK businesses unable to do "big bang" migration. Common during ISDN-to-VoIP transitions before the 2027 PSTN switch-off.
Hybrid migration →What's actually included.
Everything most UK SMEs need, bundled. The features competitors charge extra for — call recording, mobile apps, basic analytics — are included.
Call recording
GDPR-compliant call recording with searchable archives, configurable retention periods, and access controls. Critical for regulated industries (finance, healthcare, legal).
Mobile & desktop apps
Every user gets iOS, Android, Windows and Mac apps. Take business calls anywhere, transfer between devices mid-call, use your direct dial from any device.
AI Receptionist (add-on)
24/7 AI call handling trained on your business. Takes bookings, answers FAQs, qualifies enquiries, escalates urgent calls. £150/month standard tier.
IVR menus & call routing
"Press 1 for sales..." menus with intelligent routing. Time-of-day routing. Skills-based routing. Voicemail-to-email transcription. Failover paths.
Call analytics & reporting
Inbound/outbound call volumes, missed-call reports, peak-time analysis, individual user metrics, customer wait times, abandoned-call patterns. Dashboards with daily/weekly digests.
CRM integration
Salesforce, HubSpot, Microsoft Dynamics, Zoho, custom CRMs via API. Auto-popup of customer record on inbound call. Click-to-dial from CRM. Call logs auto-saved.
Microsoft Teams integration
Take business calls in Teams. Voicemail in Teams. Unified presence. Direct Routing or Operator Connect, depending on your Microsoft tenant setup.
SIP trunking
If you already have an on-premise PBX that works, SIP trunks replace the ISDN/PSTN line. Cheaper than full replacement, prepares you for 2027 PSTN switch-off.
Unlimited UK calls
All UK landline and mobile calls included on standard plans (fair-use applies on extreme volumes). International is metered separately, transparent per-minute rates.
We handle migration from any UK provider or legacy system.
The switching process is the same regardless of who you're with. We install in parallel, test, port your numbers on a scheduled cutover. Zero downtime.
Switching from BT Business
BT Business is one of our most common migration sources. CPI+3.9% annual rises, tier-1 call-centre support, slow contract changes. Honest BT vs Telexico comparison.
Full BT comparison →Switching from 4Com / Virgin
4Com, Virgin Media Business, Gamma — same migration process. We install your new system, test it, then port your numbers. Old service stays live until new is proven.
Switching process →Migrating from ISDN/PSTN
BT/Openreach switches off the old copper network in January 2027. Every UK business on ISDN must migrate. We do this every week. Migration timeline plan included.
PSTN switch-off guide →Replacing on-premise PBX
Old Avaya, Mitel, Panasonic, Samsung or NEC PBX that's reached end-of-life. We replace with modern cloud system, often re-using existing handsets where possible.

Frequently asked questions
What's the difference between a 'business phone system' and 'VoIP'?
VoIP (Voice over Internet Protocol) is the underlying technology — how voice travels (over internet rather than the old copper network). A 'business phone system' is the broader product category that uses VoIP: the handsets, mobile apps, the central call routing (PBX), the features (call recording, IVR menus, voicemail, CRM integration), the management interface. Most modern UK business phone systems are VoIP-based — but customers usually search for 'business phone systems' (what they want to buy) rather than 'VoIP' (the technology). This page is for the buyer. Our deeper technical VoIP page is at /voip-phone-systems.html if you want the engineering detail.
How much does a UK business phone system cost in 2026?
Typical 2026 UK pricing: £8-25 per user per month for a cloud-based business phone system including hosted PBX, calls (usually unlimited UK + mobile within fair-use), mobile apps, basic call recording, and a web management interface. Add-ons vary by provider: AI Receptionist £150+/month, Microsoft Teams integration +£3-8/user, advanced analytics +£4-8/user. Hardware (desk phones if needed) is typically £80-200 per phone one-off, though many businesses now work entirely from mobile/desktop apps and skip handsets. Telexico starts at £12/user/month all-inclusive — see the VoIP cost calculator for a tailored estimate.
What types of business phone systems are there?
Five main types in UK 2026. (1) Cloud-based hosted PBX — most common, everything in the cloud, scales by user count, no on-site hardware. (2) On-premises PBX — traditional, on-site server, common for larger businesses with specific compliance needs. (3) Hybrid PBX — mix of cloud and on-premises, transitional setup. (4) Microsoft Teams Phone — using Teams as the phone system via Direct Routing or Operator Connect. (5) AI-powered phone systems — AI Receptionist handling routing, basic queries, and after-hours coverage. Most UK SMEs in 2026 use cloud-based VoIP systems with AI add-ons. Telexico delivers all five.
Can I keep my existing phone numbers when switching?
Yes. UK number portability is statutory — any UK number you currently have can be ported to a new provider, usually within 5-15 working days. The porting process happens during the switch: we set up your new system in parallel with your existing one, test it, then port the numbers on a scheduled date with zero downtime. Your business doesn't lose any inbound calls during the transition. This applies whether you're switching from BT, 4Com, Virgin, Gamma, Vonage, RingCentral, or any other UK provider — and also when migrating from old ISDN/PSTN systems.
How long does business phone system installation take?
Typically 5-14 working days for a standard cloud-based system with number porting. The breakdown: 1-2 days for the initial system setup, 1-3 days for user training and configuration, 5-15 days waiting for the regulatory number port to complete (this is UK industry standard, not a Telexico delay). For multi-site rollouts, larger user counts, or specific integration requirements (CRM, custom IVR menus, Teams integration), timelines extend to 3-6 weeks. The full timeline is given in the proposal — no 'we'll be in touch in a few weeks' open-ended commitments.
What about the 2027 PSTN switch-off?
BT/Openreach is switching off the old PSTN/ISDN copper-line network in January 2027. Any business currently on PSTN or ISDN MUST migrate to a modern (VoIP-based) phone system before then. This is a UK-wide regulatory deadline — it affects every business currently on the copper network. The good news: migration from PSTN/ISDN to a modern business phone system is exactly what we do every week. We handle number porting, system setup, hardware (if needed), staff training, and the transition. The closer we get to 2027, the busier UK telecom installers will get — sooner is better than later for migration timing.
Do I need new phone hardware?
Often no. Modern UK business phone systems work via: (1) desktop apps on your computer, (2) mobile apps on your phone, (3) optional desk handsets if your team prefers them. Many UK SMEs in 2026 work entirely from apps and skip the handsets entirely (especially restaurants, retail, mobile teams). If you do want desk handsets, expect £80-200 per phone for a standard business handset, or £300-500 for premium models with colour screens, sidecar key expansion, etc. We'll recommend honestly based on your operation — many SMEs don't need handsets at all.
How does Telexico's AI Receptionist work with the phone system?
AI Receptionist is integrated into your phone system, not a separate product. Inbound calls hit the AI first (or after-hours / when nobody answers within X rings — configurable). The AI handles the call: asks what the caller needs, answers common questions trained on your business, takes bookings, captures lead details, or routes the call to a human if needed. The AI is trained on YOUR business (services, hours, pricing, FAQs) — not a generic script. Standard tier is £150/month and covers up to ~200 minutes of AI handling. For most UK SMEs missing 30-40% of calls, this typically pays back within 2-4 weeks. See the AI savings calculator for your specific numbers.
