BT One Phone for Business
BT One Phone is the cloud-based phone system that lets customers get through to your team - first time, every time. Wherever they are. Everyone can link together all their phones and devices, taking the power of their office phone wherever they go. And you can manage the whole system through a single portal, which gives you the control and flexibility you need to succeed.

Flexible working, a complex communications challenge.
There isn’t an organisation in the UK that hasn’t had to consider ‘flexible working’ in one way or another. ‘Flexible working’ is more than just a phrase – it’s a growing phenomenon and businesses need to make sure they are agile enough to keep up.
Watch BT One Phone in action
Be the business your customers expect
With our online portal, you can set-up call routing for your business. That way you can answer every customer call, no matter how busy things get. Route calls to specific teams, or based on people’s skills, so that they are always answered by the person best equipped to handle them.
Take control of your business mobiles
No matter how many mobiles there are in your business, our online portal gives you real-time control over them all. It’s easy to set up and remove users, and cancel and block SIMs. While a single voicemail for all devices makes it easier to stay on top of missed calls.
