1. Make sure that the microphone is allowed in the browser you are calling from

    To Turn on app permissions for your microphone in Windows 10

    To Control access to the microphone on Mac

2. Check if the microphone is allowed for the HighLevel web page on your browser:

    Click on the lock icon on the top right > Is microphone allowed?

3. Check if there are any Google extensions (VPN) that might block the call dialling.

Or to disable any VPN within the device

4. Check if it works using the Google chrome guest browser

We could try to use the Guest browser of Google chrome where there are no other extensions. And login to HL from the guest browser to make a call.

5. Edit the Twilio number - Outbound Call Timeout - Make sure it's more than 20 seconds and more so it will dial for longer.

6. Try to log in to on your Mobile phone's browser, not the mobile app, and see if you can call from there using the cellular data instead of the wifi network.

This will help us to know if it's device-specific or wifi-specific

7. Check if the TwiML app's location ID is correct if the location is already using a Twilio subaccount SID
