Installing the 3CX Android App

This guide takes you through the steps of installing and configuring the 3CX App for Android for versions 7.0 up to 10.0:

📄 Notes:

  • For 3CX version v15.5 PBXs you need to install the 3CX Legacy App. This version is not supported and provided as is.
  • Devices admined/jailbroken or loaded with custom ROMs are not supported.

  1. Open Google Play Store, search for 3CX and tap Install.
  2. When the app is installed, open it and Agree with the License Agreement.
  3. Follow through the “Welcome to 3CX” wizard to choose your theme, get to know your app’s features and then tap on “GET STARTED”.

💡 Tips:

  • You need to authorize the required permissions for the app when first using a feature.
  • Port 5090 TCP and UDP need to be open on your PBX, as the app connects via a secure tunnel by default to ensure end-to-end delivery in low latency environments.

Provisioning the App

To provision the app:

  1. Authorize the required camera permission and automatically configure the app by opening your Welcome Email and scanning the included QR code.

📄 Note: After opening a provisioning file for first-time automatic app configuration, you need to terminate and re-open the app.

  1. On successful provisioning, tap on “CALL ECHO SERVICE”, authorize the required permissions to place a test call to the “Echo service” and then end the call.
  2. When you see the “Ready for calls” message on the dial screen, you can start making calls.
