### Claim the next preview-mode contact for an agent

<Note>
  `GET /api/v1/dialer/next-call`
</Note>

Hands the agent frontend the next contact to review for a preview-mode campaign, atomically claiming it so two agents polling concurrently never receive the same number and double-dial. Returns the claimed contact plus the per-campaign decision countdown, `204 No Content` for progressive / predictive / agentless campaigns (their calls are originated automatically by the pacing engine), or `404` when the campaign is not active. The agent then reviews the contact and launches the call via `POST /api/v1/dialer/dial`.

<ParamField query="campaign_id" type="string">
  The active preview-mode campaign to claim the next contact from.
</ParamField>

### Originate a preview-mode dial for a claimed contact

<Note>
  `POST /api/v1/dialer/dial`
</Note>

Launches the outbound call for a contact the agent already claimed via `GET /api/v1/dialer/next-call`. Call this when the agent clicks "Call" after reviewing the preview card: the contact must still be in the `dialing` (claimed) state or the request is rejected with `409 CLAIM_NOT_HELD`. Valid only for active preview-mode campaigns — progressive / predictive / agentless campaigns dial through the pacing scheduler instead. The requesting operator is recorded as the call's agent for the TCPA audit trail. Requires the `dialer:write` scope.

<ParamField body="campaign_id" type="string">
  The active preview-mode campaign the contact belongs to.
</ParamField>

<ParamField body="contact_id" type="string">
  The dialer list-contact id returned by `GET /api/v1/dialer/next-call`.
</ParamField>
