Using Cloud Voice Express on your mobile

The app lets you make and take calls with your Cloud Voice Express business number, using your mobile device. This guide shows you how to easily activate and select numbers on the app and use its key features.

How to activate your service 

Once you’ve ordered Cloud Voice Express, you can download the app from the App Store or Google Play or scan the QR code to download directly. Or text CVEapp to 81192.

We’ll email you with the date your service will be ready. You'll also see this in the app when you log in using your My Account details. 

If you’re using a new number, we’ll activate the service and number for you.  

If you’re using an existing number, you might need to activate the service yourself, so the number gets transferred from your existing service. 

To use or activate your service, follow the instructions for plugging in and connecting your new digital phone.

Start using your new digital phone service

  1. Open the Cloud Voice Express app.
  2. Log in with your BT Business login details. (You’ll find these in your order confirmation email).
  3. Follow the steps to set up your permissions.
  4. Select Settings to set up key features.
    Or select Get started to make and take calls right away. 

Your service must be active before you can use the app on your mobile phone.

Choose a number to use when you have more than one number

If you transferred more than one phone number when you ordered Cloud Voice Express, we’ll ask you to choose which number you’d like to use.

On the Cloud Voice Express app, we’ll show the number you currently use to make and take calls.

If you’d like to change this number, simply open the drop-down and choose the number you’d like to use instead. When you’re happy, tap Select.

You can also switch between numbers while using the app. Just select the pencil next to the number at the top of the screen.

Emergency calls from the Cloud Voice Express app

We recommend you use your mobile's keypad to make 999 or 112 calls, instead of the Cloud Voice Express app.

If you call the emergency services from the app, you'll need to select the green ‘call’ key twice – once in the app, and again when the app opens your mobile’s keypad.

Features of the Cloud Voice Express app 

The app can help you with everything from diverting calls to voicemail transcripts. Find out how to use some of its key features and you’ll find more features on the Settings page.
