Set up the 3CX app on your mobile

The 3CX app lets you make and receive calls on your office number from your own phone, wherever you are. Callers see the business number, and your personal number stays private. Setting it up takes about five minutes.

What you’ll need

• your phone, connected to the internet
• a computer to show the setup code
• the welcome email from NTS with your 3CX web client link, or a link we’ve sent you

Set it up

1. On your phone, open the App Store (iPhone) or Google Play (Android) and install the 3CX app.
2. Open the app, accept the licence agreement, and allow access to the camera, microphone and notifications when it asks. The app needs the microphone for calls and the camera to scan the code.
3. On your computer, open the 3CX web client from your welcome email and sign in.
4. In the top-right corner, select the QR code button. A square code appears on the screen.
5. On your phone, scan the code with the 3CX app (on Android you can use the phone’s camera). Follow the prompts and allow the permissions shown.
6. On Android, follow the on-screen battery instructions so that calls ring when your phone is asleep.
7. Wait until the app shows Ready for calls.

Make a test call to a colleague, then ask them to ring you back, with the app closed and the phone locked.

Good to know

• The QR code button disappears after the first set-up. To add another phone later, open the Apps page in the web client to make a new code.
• Calls use your mobile data or Wi-Fi. A call uses little data, but check your data plan if you’re abroad.
• If your phone has been switched off or offline for more than about two weeks, set the app up again with a new code.
• Keep your phone’s software up to date.
• If you lose your phone, tell us straight away so we can remove it from the phone system.

If it doesn’t work

• The code won’t scan. Hold the phone steady about 20 cm from the screen, and make the code bigger on the screen. Check the camera is allowed for 3CX in your phone’s settings.
• Your phone doesn’t ring when the app is closed. Check that notifications are allowed for 3CX, and that battery saving isn’t turned on for the app.
• Callers can’t hear you. Check that the microphone is allowed for 3CX in your phone’s settings, then restart the app.
• The app says it isn’t registered. Check that the phone has internet, then close and reopen the app. If it still fails, email us and we’ll send a fresh code.
• There’s no QR code button. Open the Apps page in the web client, or ask us to send a new one.
