Troubleshooting AI Dialer setup, microphone and phone number problems

Learn how to fix a microphone, audio device or phone number problem that stops the AI Dialer from placing calls.

Overview

Before the AI Dialer can place a call it needs two things: a phone number assigned to you and a microphone it is allowed to use. When either is missing, the call does not start and a notification explains why. A phone number is chosen on the Dialer page in Settings or in the Select a Phone Number window that opens on your first call.

Fix a microphone problem

1. Open your browser's site settings for GTM One and set the microphone to Allow. In the Chrome extension, allow microphone access in Chrome.
2. Check that your microphone is plugged in and is not in use by another app that blocks it.
3. Reload GTM One.
4. Open Settings, click Dialer, and confirm the microphone and speaker you want are selected. See How to choose your microphone and speaker for calls.
5. Click the call button again.

Fix a phone number problem

1. Open Settings and click Dialer.
2. In the My Phone Number card, check whether a number is shown. If not, click Select Phone Number.
3. In the Select a Phone Number window, choose an area code, choose a number, and click Done. If the area code or the number is refused, choose a different one.
4. Reload GTM One and place the call again.

See How to choose your dialer phone number for the full steps. Sound and voicemail settings stay unavailable until you have a number.

Fix an audio device problem

1. Reconnect the headset or microphone you selected.
2. Open Settings, click Dialer, and choose the microphone and speaker again.
3. Reload GTM One and call again.
