Answer

Sent when the call is answered, that is when the conversation actually begins. You can start your talk time measurement from this moment.

Sample body

scenario: Answer

{
  "pbx_num": "8501234567",
  "unique_id": "sip1-1767225600.10001",
  "internal_num": "100",
  "incoming_number": "8501234567",
  "scenario": "Answer",
  "customer_num": "05551112233",
  "holdtime": "16",
  "timestamp": "1767225616000"
}

Send this body to your own address

The sample body above is sent to the address below as a POST request. The request goes from your browser, so the response cannot be read if the receiving endpoint sends no CORS header; the request itself still arrives. Use the cURL equivalent to try it from the server side.

cURL equivalent:

curl -X POST 'https://your-address.example/webhook' \
  -H 'Content-Type: application/json' \
  -d '{"pbx_num":"8501234567","unique_id":"sip1-1767225600.10001","internal_num":"100","incoming_number":"8501234567","scenario":"Answer","customer_num":"05551112233","holdtime":"16","timestamp":"1767225616000"}'

Fields

Field	Type	Description
scenario	string	Always Answer.
pbx_num	string	Your PBX number.
unique_id	string	Unique identifier of the call.
internal_num	string	The extension that answered the call.
incoming_number	string	Your number that was dialed.
customer_num	string	Subscriber number on the other side.
holdtime	string	Wait time until the call was answered, in seconds.
timestamp	string	Event time (ms, Unix epoch).

Telling an answered call apart

The simplest way to know whether a call was answered is to check whether this event arrived: if no Answer event ever came for a given unique_id, the call was not answered.
