The most versatile business Cloud PBX solution you can buy

CallSwitch enables teams to connect and collaborate in the ways that work best for them, through voice, video, instant messaging, call recording, online meetings, screen sharing, and much more.

Built for modern working

With a host of ways to connect, through desktop clients, mobile apps, and traditional desk phones, CallSwitch is designed for office, home, and hybrid working environments.

Competitive licencing

We don’t believe in charging extra for features that should come as standard, whether that’s Apps, call recording, or integrations, and our inclusive call bundles keep you protected.

Intelligent integration

Key to any Unified Communications solution is integration with other critical services. CallSwitch integrates with all the leading CRM platforms ‘out of the box.’

CallSwitch Communicator phone system UCaaS

Powerful applications that simplify communication

Communicator is available for desktop (Windows and Mac OS), and mobile (iOS and Android), delivering a host of communication and collaboration features within a single intuitive pane, including softphone, video, messaging, screen and document sharing, group conferencing, and presence.

Integrate with all the tools you need

Less common, web-based, CRMs are also catered for, offering both click-to-dial and ‘screen pop’ functionality.
