BT One Phone brings together your desk phones, mobile phones, and phone system into a single hosted service so all of your calls and voicemail go to just one mobile device.

There are two members of the BT One Phone family: BT One Phone Office and BT One Phone Professional.

BT One Phone Office replaces your office phone system with a Cloud-based one. A dedicated private mobile network, installed in your office, gives guaranteed mobile coverage and capacity – so you can use your mobiles without fear of losing signal, and with guaranteed call quality. And as you move away from the office, calls are transferred seamlessly to the BT Mobile network. Your people will have access to all the call management features they expect from their desk phones, through their mobiles.

BT One Phone Professional uses the BT One Phone Cloud-based phone system to give your mobile workers the same access to call management features that they rely on in the office, no matter where they are in the UK. (Does not replace your office phone system).

BT Cloud Voice is a virtual phone system hosted in the cloud, so no more hardware or maintenance (we do that for you). The clever bit is that all your calls are made over the internet. You just need a BT Business internet connection.

It’s got all the features of a traditional phone system but it also lets you work from whatever device you choose. And that’s from any location, in or out of the office, as long as you’re online. Calls are crystal clear, it’s more flexible and it’s more cost efficient. In business terms, it’s a win-win.

BT Cloud Voice is super-useful across a range of tasks. You can talk to colleagues for free wherever they are using the cloud, redirect your calls when you’re out of the office and manage your calling features from any device, anywhere, using the online portal. It has more sophisticated call features like call recording, call centre, and audio and web conferencing that you can add for anybody who needs them.

Here’s a rundown of the top reasons we think it’s so nifty:

  • Manage calls more effectively
  • Be more productive; your people can receive and make calls when out of the office more easily
  • Control your costs by creating a bespoke package for each user
  • Get market-leading products you can trust with BT Business
  • Future-proof your business, scale up as you need to
  • Get peace of mind with our UK-based, dedicated BT Cloud Voice expert team
  • Manage your entire voice estate in a single solution
