Choose a supported setup
Start with the current Message Apps and Phone setup guidance. Calling behavior depends on the app or browser, device permissions and configured phone service.
Check permissions
Allow microphone access for the supported calling surface. Confirm the intended audio input and output, and check whether system settings suppress notifications.
Test both directions
Place a test call and receive one. Verify audio, call controls, background behavior and what happens when the device loses its connection. Do not treat a successful login as a completed calling setup.
Use another route if needed
Keep an alternative supported device or phone route available until you have verified the mobile setup. Share the device, browser version and call ID with support if a test fails.
Keep going
Put the next step into practice, or ask us about your setup.
