How to intercept Hangup on Originate?

Question

Asterisk

Good afternoon!
There is a certain Web service which through AMI executes Originate and is disconnected.
I need to perform some actions in the dialplan at the end of the conversation of subscribers. How can I catch the Hangup of such a call? If you place the h extension in one of the Originate contexts, then it will work at the moment the two channels connect.

Answer 1

It was possible to get the necessary interaction using the Local channel with the key n - the channel existed until the end of the call and jumped normally to the h extension.
