How to highlight an Asterisk event?

Question

Asterisk

Hello. Interested in one thing. How to make a certain event (namely, a call to a PHP script) fire when a conversation starts? How can this be done in extensions? That is, there is a dial-up, as soon as the phone is picked up, the script is triggered.

In general, you need to trigger on several events - a call arrives (when it just arrived and has not yet been sent to some queue), "waiting" (when it has already been directed to the queue and there is a call to queue subscribers), the beginning of a conversation, the end of a conversation.
