Initiate Call

POST https://example.com/call

Initiate an outbound notification call.

The call will be made asynchronously. If callback_url is provided, results will be POSTed there when the call completes.

Calls are queued and processed sequentially to prevent overwhelming the SIP system.

Note: callback_url is required when using choice collection.

Simple notification example:

{
    "message": "Hello, this is a reminder about your appointment.",
    "extension": "1001"
}

Choice collection example (requires callback_url):

{
    "message": "Hello, this is a reminder about your appointment tomorrow at 2pm.",
    "extension": "1001",
    "callback_url": "https://example.com/webhook",
    "choice": {
        "prompt": "Say yes to confirm or no to cancel.",
        "options": [
            {"value": "confirmed", "synonyms": ["yes", "yeah", "yep", "confirm"]},
            {"value": "cancelled", "synonyms": ["no", "nope", "cancel"]}
        ],
        "timeout_seconds": 15
    }
}
