    • The input addresses people (input.to): what it sends cannot be taken back.
    Description, as the server wrote it
    Place an outbound AI phone call to set up a meeting. The assistant calls the person, agrees a time, and the result (poll get_call) carries outcome (appointment_set | callback_requested | declined | no_answer | failed) and, when set, the appointment (startISO, timezone, durationMinutes, attendee, subject). Returns a callId immediately.
