Hear a switchboard line before a caller does (SES-1 F5)
POST/api/channels/:channel/calls/switchboard/preview
Synthesizes one of the switchboard's spoken lines — the out-of-hours greeting or the voice menu — and returns a short-lived signed link to the audio.
Deliberately on the switchboard's own routes rather than the Meta-side
calling settings: previewing your own greeting must not require a
working Graph token. Admin-gated (Channel update).
