}Initiate outbound call POST
Initiates an outbound Business-Initiated Call. The Telnyx-side SIP leg is originated server-side (Option B: SIP-first). Telnyx INVITEs Meta directly over TLS:5061 with the SIP digest credentials we captured at calling-enablement time). No client-side SDP is required; pass only `accountId` and `to`. To send the consumer the call-consent prompt instead of placing a call, pass `action: "send_call_permission_request"` (+ optional `bodyText`). The consumer must tap Allow in WhatsApp before `start_call` is permitted; Meta limits the prompt to 1 per consumer per 24h (2 per 7 days) and requires an open 24h service window.
Estimate per-minute cost GET
Returns a zero-markup estimated cost for an outbound call to the given destination, broken down by Meta + Telnyx + recording line items. Costs are pass-through, no margin applied.
