A:Answer Hello Janster,
Echo Dot or other Echo devices doesn't support calls for emergency service numbers like "911." Buy you can use Drop In to instantly check-in with others in your household. Drop In is an optional feature that lets you connect instantly to supported Alexa-enabled devices, like an intercom. Use Drop In to open an instant conversation between your devices or with your Alexa contacts. When you receive a Drop In, the light indicator on your Echo pulses green and you connect to your contact automatically. You can use Drop In to:
1. Have a two-way conversation by connecting to one of your Alexa-enabled devices (""drop in on Kitchen"").
2. Connect to a specific device group (""drop in on living room""). Only one Alexa-enabled device from the device group connects.
3. Have a group conversation with all supported Alexa-enabled devices under your Amazon household, which are not set to do not disturb. To start a group conversation ask Alexa to Drop In everywhere. All supported Alexa-enabled devices under your Amazon household account will connect regardless of their physical location.
4. Drop In on a contact who granted you Drop In permissions.
5. Receive Drop In from a contact whom you granted Drop In permissions.
Thanks for the question. Have a great day!
