Start a connected app voice call
See Voice SDK integration for authentication, platform packages, routing, and preview availability. The SDK calls this after joining and publishing microphone audio. Use Authorization: Bearer <controlToken> from call creation. Only this OpenCX call token is accepted for call control; permanent API keys are not accepted. Use the SDK to manage the audio connection before activation. Returns HTTP 200 with { "success": true }. Repeated activation of an active call is safe. Expired or ended calls, missing microphone publication, and unavailable support return 409. A failed activation ends its reserved call; begin a new call attempt with a new request ID.
