QueueLeave

Sent when the call leaves the queue. Leaving can happen in two ways: the call was connected to an agent, or the caller gave up waiting and hung up.

The holdtime field gives you how many seconds the call waited in the queue; it is the input for your average wait time and abandon rate calculations.

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 '{"queue_name":"8501234567-queue-destek","pbx_num":"8501234567","unique_id":"sip1-1767225600.10001","incoming_number":"8501234567","scenario":"QueueLeave","customer_num":"05551112233","holdtime":"14","timestamp":"1767225614000"}'

Fields

Field	Type	Description
scenario	string	Always QueueLeave.
queue_name	string	Full name of the queue that was left.
pbx_num	string	Your PBX number.
unique_id	string	Unique identifier of the call.
incoming_number	string	Your number that was dialed.
customer_num	string	Calling subscriber number.
holdtime	string	Time waited in the queue, in seconds.
timestamp	string	Event time (ms, Unix epoch).

This event alone does not tell you about abandonment

QueueLeave on its own does not say whether the call was answered or abandoned. To tell them apart, check whether an Answer event follows for the same unique_id; if it does not, the call was left unanswered. For a definitive answer use the sondurum field of the cdr event.
