Hereafter, the 'A call comes in' Webhook is needed:

From here, you can click on the number to enter it's settings, Copy and paste the webhook shown above into the 'A Call Comes In' field.
Please note that the Dialog Managers flows that are pushed to production are triggered when testing.
Several settings are available for your voice bot, such as the expected voice-to-text language of the voice bot user, the desired voice-to-text language for the content stored in the dialog manager. Also the timeout settings to reply to a question from the bot using either voice or phone buttons can be found here. On top of that, the preferred voice of the voice bot can be adjusted and a timeout message can be made to tell the user it has used all time until the timeout.
