No, it lets the recipient of the call see the caller, so they can choose to answer or not. It does not let the caller see who they are calling before they answer. Also the tape on your laptop won't matter since it is phone only for now.

It responds to a call by accepting the connection and a payload (video) before the user has decided whether to "accept" the call?

"... since it is phone only for now."

For now?

Yikes.
