/**
 * Campaign outbound that starts at INVITE (`outboundCallMode: 'from_invite'`).
 *
 * The host raises the script first, then dials the campaign number on the same
 * `channel`. 1xx lands on `progress$`; a 4xx/5xx rejects `waitForAnswer()`.
 * Gate the greeting on the answer so it does not play into ringback.
 *
 * `getScriptPhase` stays `'early'` for the whole live run. Read
 * `channel.sip.isAnswered` for the live state. Billing stays on the 200 OK.
