32 \brief The AMI - Asterisk Manager Interface - is a TCP protocol created to
33 manage Asterisk with third-party software.
35 Manager protocol packages are text fields of the form a: b. There is
36 always exactly one space after the colon.
40 The first header type is the "Event" header. Other headers vary from
41 event to event. Headers end with standard \r\n termination.
42 The last line of the manager response or event is an empty line.
47 ** Please try to re-use existing headers to simplify manager message parsing in clients.
48 Don't re-use an existing header with a new meaning, please.
49 You can find a reference of standard headers in doc/manager.txt
