/**
 * When the host hands a platform-dialed outbound leg to the script.
 *
 * - `'on_answer'` — the host dials and starts the script on the `200 OK`. The script
 *   always gets an answered call, which is what a greeting, a turn watchdog and a
 *   max-duration timer assume.
 * - `'from_invite'` — the host starts the script **first**, then automatically
 *   dials the campaign number on the same `channel`. The session is already
 *   running when the INVITE goes out, so `progress$` / `sipSignal$` see 1xx and
 *   a 4xx/5xx rejects `waitForAnswer()`. Phase is `'early'`; gate the greeting
 *   on `channel.sip.waitForAnswer()`.
 * - `'script_dial'` — the host does **not** dial. The script starts with no leg at all
 *   (phase `'dialing'`) and opens one itself:
 *
 *   ```ts
 *   const leg = await channel.sip.makeCall({ msisdn: context.calledNumber });
 *   await leg.sip.waitForAnswer();
 *   ```
 *
 *   The leg it gets back is the conversation channel — the one the script plays and
 *   listens on. The channel the script starts with can only dial: it has no audio.
 *   The first leg opened this way is the one the platform reports on (result,
 *   `answer_date`, duration, recording), so a script that never dials leaves the
 *   call row with no answer.
 *
 * Inbound legs are unaffected — they always start before the answer. `'from_invite'`
 * additionally lets an inbound run report `'early'` instead of `'online'`.
 *
 * `answer_date` and billing never move: both come from the `200 OK`.
