Call one private person and relay one message from the user.

Ask the user to confirm the recipient, E.164 number and exact spoken message first, then set user_confirmed=true. original_message is the user's unedited request; message is the faithful sentence spoken aloud. Both are screened. The AI identifies itself and passes on the message; this tool is not an open-ended conversation or a broadcast tool.

Requires the user's verified, enabled outbound Caller ID. Call caller_id_status for readiness and setup link. Verification means answering a call and entering a code; call_me uses a separately selected receiving number. Never substitute call_business for a private recipient. If the Caller ID is refused by the carrier, the call fails without a platform-number retry. Up to 10 private calls per account per rolling 24h. Billed per minute. Reuse the same idempotency_key to recover this attempt; wait_for_call if in_progress. Only after a terminal no-answer or busy result with no contact should your workflow consider another call, using a new key and respecting the user's instructions and the recipient's local time. Do not redial a failed result because it does not establish that nobody was reached.
