Detailed Description

The AMI - Asterisk Manager Interface - is a TCP protocol created to manage Asterisk with third-party software.

Manager protocol packages are text fields of the form a: b. There is always exactly one space after the colon.


 For Actions replies, the first line of the reply is a "Response:" header with
 values "success", "error" or "follows". "Follows" implies that the
 response is coming as separate events with the same ActionID. If the
 Action request has no ActionID, it will be hard matching events
 to the Action request in the manager client.

 The first header type is the "Event" header.  Other headers vary from
 event to event.  Headers end with standard \\r\\n termination.
 The last line of the manager response or event is an empty line.
 (\\r\\n)

Note:
Please try to re-use existing headers to simplify manager message parsing in clients. Don't re-use an existing header with a new meaning, please. You can find a reference of standard headers in doc/manager.txt

Definition in file manager.h.
