How to Set Up the 3CX Mobile App

The 3CX mobile app turns your smartphone into a full business extension. Calls show your business number to the recipient — not your personal cell number.

What You’ll Need

  • Your smartphone (iOS or Android)
  • Your 3CX welcome email from DVGVoIP (contains your provisioning QR code)
  • A Wi-Fi or cellular data connection

Step 1: Download the App

Search for 3CX in the App Store (iPhone) or Google Play Store (Android) and install it. The app is free.

Step 2: Scan Your Provisioning QR Code

DVGVoIP sends every new user a welcome email containing a QR code. This code automatically configures the app with your extension settings.

  1. Open the 3CX app
  2. Tap Scan QR Code
  3. Point your camera at the QR code in your welcome email
  4. The app will configure itself automatically

Tip: If you can’t find your welcome email, contact DVGVoIP at solutions@dvgvoip.com and we’ll resend your provisioning code.

Step 3: Allow Notifications

When prompted, allow the app to send notifications. This ensures your phone rings when a business call comes in, even when the app is in the background.

On iPhone, go to Settings → 3CX → Notifications and enable Allow Notifications.

Step 4: Test a Call

  • Incoming: Have someone call your business number. Your mobile app should ring along with your desk phone.
  • Outgoing: Open the 3CX app, tap the dial pad, and make a call. The recipient will see your business number.

Adjusting Your Status

The app shows your availability to colleagues:

  • Available — you’ll receive calls
  • Away — calls still route to you but colleagues can see you’re away
  • Do Not Disturb — calls go straight to voicemail

Tap your name or avatar at the top of the app to change your status.

Transferring Calls on Mobile

To transfer a call to a colleague:

  1. While on a call, tap Transfer
  2. Choose Blind Transfer (immediate) or Attended Transfer (announce first)
  3. Dial the colleague’s extension or select from your contacts
