already_answered

Already answered · HTTP 409

The call was answered or declined first by someone else — another invitee, or another tab or device of the same identity.

What to do: Dismiss the incoming-call UI. The SDK ends that call on its own with answered_elsewhere when another session of this identity answered.

Where it comes from:

• Control API
• Signaling — a client's connect, a request, or an event

Branch on code; detail is for your logs and never for a user. All error codes.
