Yes. There are also three ways to limit incoming calls.
Do Not Disturb: You can use Do Not Disturb in the Alexa app settings to stop incoming calls from ringing on your device.
Away Mode: The Away Mode in the Alexa app can be used to control when incoming calls on Alexa devices ring. When Away Mode is enabled, Alexa devices will not ring and you will not be able to make outbound calls using AT&T (except to emergency services) if your mobile phone is more than approximately 490 feet (150 meters) away from the registered emergency address. Your location is determined based on the location information of your mobile phone.
Routines: You can set up Routines with the action of limiting incoming and outgoing calls. For example, Routines can be set based on utterances, such as “Alexa, I’m leaving home,” or be schedule-based, such as 9 a.m. to 5 p.m. each weekday.
