Cloud PBX / central control
Cloud PBX and virtual PBX systems for UK businesses.
Run extensions, call routing, queues and administration from a hosted PBX while users work from office phones, desktop apps or mobiles. A cloud PBX gives the business one call-control layer without putting a PBX appliance in every office.

What this can include
Cloud PBX is about control of the call engine.
A cloud PBX is most useful when you need clear control over extensions, trunks, routing rules, queues, recording, permissions, integrations and multi-site administration.
Bring sites under one dial plan
Centralise users and routing while allowing each location to keep the endpoint mix and numbers it needs.
Connect communications workflows
Use supported CRM, directory or Teams integrations where they remove duplicate work for users.
Retain meaningful system control
Give authorised administrators visibility into users and call handling without maintaining PBX hardware at each site.
Designed around the workplace
Centralise the PBX without flattening every site.
A cloud PBX can bring extensions, queues, permissions and routing under one administration model while different locations keep the endpoint mix and local call handling that suit them.

Is it right for you?
Where this option works best.
Cloud PBX suits SMEs that need more explicit PBX control than a basic hosted-phone bundle but do not want a separate physical PBX appliance at every location.
Choose this when
You need centralised PBX configuration, multi-site routing, richer call handling, reporting or integrations and want the core platform hosted.
Consider another route when
If simplicity and provider management matter more than PBX-level control, compare Hosted VoIP/Hosted Telephony. If you prefer appliance or software deployment choice, see Yeastar P-Series.

Common questions
Frequently asked questions.
Short answers to the questions we are most often asked about this type of system.
What is a cloud PBX?
A cloud PBX provides PBX functions such as extensions, routing, queues and administration from a hosted platform rather than a traditional PBX installed at each office.
How is Cloud PBX different from hosted VoIP?
The terms overlap. Cloud PBX usually puts more emphasis on PBX-level control, while hosted VoIP is often delivered as a broader managed phone service.
Can a cloud PBX serve multiple sites?
Yes. A well-designed system can centralise dial plans and routing while supporting users and numbers across different locations.
Can Cloud PBX integrate with Microsoft Teams?
Supported integrations depend on the PBX platform and deployment. With Yeastar P-Series, Teams integration can be designed for users who benefit from working inside Teams.
