BT Cloud Voice

Hosted telephony solution that brings cloud benefits to voice and Unified Communication and Collaboration (UC&C) services

What is BT Cloud Voice?

A hosted PBX solution, BT takes telephony to the cloud to simplify communications while empowering your business with Unified Communications and contact centre capabilities.

Managed by BT as a pay-as-you-go service, it turns communications into an operational rather than capital cost while giving you the resilience and flexibility you need to support a fast changing business.

Why now?

To stay competitive in an increasingly connected world, organisations need cost-effective telephony that offers more features and functionality. Not only does BT Cloud Voice achieve this, it provides a stepping-stone to Unified Communication and Collaboration (UC&C) services that are more complex and costly to run on premise.

How do you start?

Depending on where you are in your business lifecycle – looking to replace an end-of-life PBX, for example, or needing a new one to support a greenfield site – BT Cloud Voice is an easy step to take. Hosted and managed by BT, you relieve your organisation of the time and resources needed to manage it internally.
