What is a hosted phone system?
A hosted phone system is a cloud-based business telephone system. Instead of a physical PBX box on your premises, all the switching and call management happens in the cloud — managed by your provider. Calls are made over your broadband connection using VoIP (Voice over Internet Protocol).
Users can make and receive calls from desk phones, mobile apps, desktop apps, or a web browser — all on the same system, all on the same number. You manage everything from a web portal: add users, set up call routing, build IVR menus, configure voicemail — no engineer, no waiting on hold to your provider.
Works on any device
Desk phones, mobile apps (iOS and Android), Windows and Mac desktop clients, and a WebRTC browser client. One system, every device.
Zero-touch provisioning
New handsets are auto-configured when plugged into your network. No engineer visit required. A 10-user system can be live in hours.
Full management portal
Add and remove users, configure DDI numbers, build IVR menus, set call routing rules and time profiles — all from a web browser.
Call recording
Applied to individual users, groups, or the whole account. PCI-DSS compliant pause-and-resume. Stream or download from the portal.
Live reporting
Real-time dashboards, call volumes, answer rates, agent performance, inbound and outbound breakdown. Export any report to CSV.
CRM integration
Integrates with over 200 CRM systems. Microsoft Teams presence integration. WhatsApp Business messaging available as an add-on.
How much does a hosted phone system cost?
Hosted phone systems are priced per user per month. You only pay for what each person actually needs — a receptionist, a field worker, and a contact centre agent all have different requirements and can be on different plans.
Typical costs broken down
| Cost item | Typical range | Notes |
|---|---|---|
| Monthly licence — app only Most popular | £9.99/user/month | Includes UK number, UK landline and mobile calls, iOS, Android, Windows and Mac apps, voicemail to email, call recording |
| Monthly licence — with desk phone | From £12.95/user/month | Includes everything above plus a Cisco, Grandstream, or Yealink handset. Auto-provisioned — plug in and it works. You own the hardware. |
| Setup fee | £0 for self-install | Zero-touch provisioning means no engineer visit is required. Porting charges and optional programming time are the only additional costs. |
| Number porting | Fixed charge per number | Transfer your existing business numbers. Geographic (01/02/03) and non-geographic (08) numbers supported. Typically 5–15 working days. |
| Optional programming | Hourly rate | IVR menus, call routing, time plans, and complex configurations. Simple setups can be self-managed via the portal at no extra cost. |
| Add-ons | Quoted per requirement | Advanced reporting, ACD/call centre, Microsoft Teams integration, WhatsApp Business, CRM integration (200+ systems). Pay only for what you use. |
