How does the Watch handle voice calls?

[a042349]

I've seen NOTHING about how the Watch interacts as a phone call manager.

What does an incoming call do? Speakerphone? Send to voicemail/txt response? Answer on iPhone? Do BT headsets work with it? Etc, etc.

How about outgoing calls? Siri, probably. Dialer maybe?

Any ideas or links to how voice calling is handled?

There really is a lot of unanswered questions. Remember all of the health sensors it was supposed to have? Now we are only hearing about one, HRM.

Phone. Use the built-in speaker and microphone for quick chats, or seamlessly transfer calls to your iPhone for longer conversations. You can also transfer calls from Apple Watch to your car’s speakerphone or your Bluetooth headset. And silence incoming calls by covering Apple Watch with your hand.
