3CX

3CX V20 Call Control API (HTTPS /callcontrol + /callcontrol/ws). Service Principal client_credentials via POST /connect/token. Requires 3CX 8SC+ Enterprise and Call Control API access. XAPI GET /xapi/v1/Users is used for extension identity when the principal has Configuration API rights. Not a SIP stack. PHP-FPM cannot hold the Call Control WebSocket; a worker must pump frames into generic Realtime ingest. HTTP webhooks are not the official event channel. Hold/resume, recordings, queues, and presence are not in the public Call Control endpoint set.
