The VoIPCloud Webphone mobile app turns your smartphone into a full business phone extension. Make and receive calls using your office number from anywhere with an internet connection.
Installing the App
Search for VoIPCloud in the Apple App Store (iOS) or Google Play Store (Android). Download and install the free app. Open it after installation.
Entering Your Credentials
Tap Configure Account. Enter your Extension Number, Password, and SIP Domain from your VoIPCloud portal Welcome email. Tap Save to register. The status bar should show Registered.
Granting Permissions
Allow the app access to your Microphone (required for calls) and Notifications (required to receive calls when the app is in the background). On iOS, also enable Background App Refresh for the Webphone app.
Push Notifications
The app uses push notifications to wake when an inbound call arrives, even when closed. Ensure notifications are enabled in your device Settings. On Android, disable battery optimisation for the Webphone app to prevent missed calls.
Wi-Fi vs Mobile Data
For best quality, use Wi-Fi. When on mobile data (4G/5G), the app will use the VoIPCloud media relay to traverse carrier NAT. Calls on 4G are reliable in most metropolitan areas. Some corporate Wi-Fi networks may block SIP — contact your IT team if calls fail on company Wi-Fi.
