There is + always exactly one space after the colon. + +\verbatim + + 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) + +\endverbatim + + \note Please try to \b re-use \b existing \b 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 + +- \ref manager.c Main manager code file + */ + +#define AMI_VERSION "1.1" +#define DEFAULT_MANAGER_PORT 5038 /* Default port for Asterisk management via TCP */ + +/*! \name Manager event classes */ +/*@{ */ +#define EVENT_FLAG_SYSTEM (1 << 0) /* System events such as module load/unload */ +#define EVENT_FLAG_CALL (1 << 1) /* Call event, such as state change, etc */ +#define EVENT_FLAG_LOG (1 << 2) /* Log events */ +#define EVENT_FLAG_VERBOSE (1 << 3) /* Verbose messages */ +#define EVENT_FLAG_COMMAND (1 << 4) /* Ability to read/set commands */ +#define EVENT_FLAG_AGENT (1 << 5) /* Ability to read/set agent info */ +#define EVENT_FLAG_USER (1 << 6) /* Ability to read/set user info */ +#define EVENT_FLAG_CONFIG (1 << 7) /* Ability to modify configurations */ +#define EVENT_FLAG_DTMF (1 << 8) /* Ability to read DTMF events */ +#define EVENT_FLAG_REPORTING (1 << 9) /* Reporting events such as rtcp sent */ +#define EVENT_FLAG_CDR (1 << 10) /* CDR events */ +#define EVENT_FLAG_DIALPLAN (1 << 11) /* Dialplan events (VarSet, NewExten) */ +/*@} */ + +/*! \brief Export manager structures */ +#define AST_MAX_MANHEADERS 128 + +/*! \brief Manager Helper Function */ +typedef int (*manager_hook_t)(int, const char *, char *); + + +struct manager_custom_hook { + /*!
