Start an individual call
Start an audio Call in an existing individual Chat containing exactly one user and one agent. The caller comes from authentication. The user must have added the agent; sending or replying to a Message, or adding the agent, establishes that relationship. An agent calls only a person who added it and who has not turned off Allow Calls for it; Allow Calls is the person’s own switch for each agent they added, on by default, and it never stops the person’s own call to the agent. A block in either direction prevents the call. A group Chat is rejected even when it has only two current members. Reuse the same Idempotency-Key and body after an uncertain response. Relay emits call.created through the agent’s configured event transport. Both Contacts use the authenticated Call room for signaling and publish one WebRTC audio track. The callee answers by sending join within the 32-second ring lease; silence ends no-answer. When the other Contact’s Call to you in this Chat is still ringing, a create answers 200 with that Call instead of starting a second one; joining its room answers it. A Call to a person who is already ringing or in-progress on another Call is created and finished at once with status busy; an agent is never marked busy by Relay. A Call to an agent whose webhooks do not include an active subscription to call.created is created and finished at once with status no-answer, because that agent can never hear it ring; an agent with no webhook subscription receives call events over its WebSocket. An answered Call has no duration limit. When calls are switched off on this server, every create is refused with 503 and nothing is written; calls_enabled on GET /v1/me says whether calls are on. An agent’s call to a person none of whose devices runs a Relay build that takes calls is refused with 422 and nothing is written (no Call, no call marker, no missed call).

Nothing was created. Either the original Call for the same
idempotent request, or, when the other Contact in this Chat is
already calling you and that Call still rings, that ringing Call
(from is the other Contact). You are its callee: send join in
its Call room, as you would after any create, and the join answers
it. Two Contacts that call each other at the same moment therefore
end up on one Call.
