AELSub

Launch subroutine build with AEL.

Execute the named subroutine, defined in AEL, from another dialplan language, such as extensions.conf, Relaltime extensions, or Lua. The purpose of this application is to provide a sane entry point into AEL subroutines, the implementation of which many change from time to time. 

AELSub(routine,[args])
  • routine : Named subroutine to execute.
  • args

AgentLogin

agent login 을 한다.

Login an agent to the system. Any agent authentication is assumed to already be done by dialplan. While logged in, the agent can receive calls and will hear the sound file specified by the config option custome_beep when a new call comes in for the agent. Login failure will continue in the dialplan with AGENT_STATUS set.

Before logging in, you can setup on the real agent channel the CHANNEL(dtmf-features) an agent will have when talking to a caller and you can setup on the channel running this application the CONNECTEDLINE() information the agent will se while waiting for a caller. 

AgentLogin(AgentId,[options])
  • AgentId
  • options
s : silent login. do not announce the login ok segment after agent logged on.

Channel variables

  • AGENT_STATUS enumeration values.
INVALID : The specified agent is invalid.
ALREADY_LOGGED_IN : The agent is already logged in.

See also

AgentRequest

Request an agent to connect with the channel.

Request an agent to connect with the channel. Failure to find, alert the agent, or acknowledge the call will continue in the dialplan with AGENT_STATUS set. 

AgentRequest(AgentId)
  • AgentId

Channel variables

  • AGENT_STATUS : enumeration values
INVALID : The specified agent is invalid.
NOT_LOGGED_IN : The agent is not available.
BUSY : The agent is on another call.
NOT_CONNECTED : The agent did not connect with the call. The agent most likely did not acknowledge the call.
ERROR : Alerting the agent failed.

AGI

Executes an AGI compliant application.

Exectes an Asterisk Gateway Interface compliant program on a channel. AGI allows Asterisk to launch external programs written in any language to control a telephony channel, play audio, read DTMF digits, etc. by communicating with the AGI protocol. 

AGI(command,arg1,[arg2[,...]])
  • command : How AGI should be invoked on the chaneel.
  • args: Arguments to pass to the AGI script or server.
arg1
arg2[,arg2...]

The following variants of AGI exist, and are chosen based on the value passed to command.

  • AGI : The classic variant of AGI, this will launch the script specified by command as a new process. Communication with the script occurs on stdin and stdout. If the full path to the script is not provided, the astagidir specified in asterisk.conf will be used.
  • FastAGIj : Connect Asterisk to a FastAGI server using a TCP connection. The URI to the FastAGI server should be given in the form [scheme]://host.domain[:port][/script/name], where scheme is either agi or hagi. In the case of hagi, an SRV lookup will be performed to try to connect to a list of FastAGI servers. The hostname in the URI must be prefixed with _agi._tcp. prior to the DNS resolution. For example, if you specify the URI hagi://agi.example.com/foo.agi the DNS query would be for _agi._tcp.agi.example.com. You will need to make sure this resolves correctly.
  • AsncAGI : Use AMI to control the channel in AGI. AGI commands can be invoked using the AMI action, with a variety of AGI specific events passed back over the AMI connection. AsyncAGI should be invoked by passing agi : async to the command parameter.

Channel variables

  • AGISTATUS : The status of the attempt to the run the AGI script text string.
SUCCESS
FAULURE
NOTFOUND
HANGUP

Example

  • AGI invocation examples
; Start the AGI script /tmp/my-cool-script.sh, passing it the contents
; of the channel variable FOO
same => n,AGI(/tmp/my-cool-script.sh,${FOO})
 
; Start the AGI script my-cool-script.sh located in the astagidir
; directory, specified in asterisk.conf
same => n,AGI(my-cool-script.sh)
 
; Connect to the FastAGI server located at 127.0.0.1 and start the script
; awesome-script
same => n,AGI(agi://127.0.0.1/awesome-script)
 
; Start AsyncAGI
same => n,AGI(agi:async)

AlarmReceiver

Provide support for receiving alarm reports from a burglar or fire alarm panel.

This application should be called whenever there is an alarm calling int to dump its events. The application will handshake with the alarm panel, and receive events, validate them, handshake them, and store them until the panel hangs up. Once the panel hang up, the application will run the system command specified by the eventcmd setting in alarmreceiver.conf and pipe the events to the standard input of the application. The configuration file also contains settings for DTMF timing, and for the loudness of the acknowledgemnet tones. 

AlarmReceiver()

Channel variables

  • ALARMRECEIVER_CALL_LIMIT : Maximum call time, in milliseconds.
If set, this variable causes application to exit after the specified time.
  • ALARMRECEIVER_RETRIES_LIMIT : Maximum number of retries per call.
If set, this variable causes application to exit after the specified number of messages.

Configuration

/etc/asterisk/alarmreceiver.conf 

;
; alarmreceiver.conf
;
; Sample configuration file for the Asterisk alarm receiver application.
;


[general]

;
; Specify a timestamp format for the metadata section of the event files
; Default is %a %b %d, %Y @ %H:%M:%S %Z

timestampformat = %a %b %d, %Y @ %H:%M:%S %Z

;
; Specify a command to execute when the caller hangs up
;
; Default is none
;

;eventcmd = yourprogram -yourargs ...

;
; Specify a spool directory for the event files. This setting is required
; if you want the app to be useful. Event files written to the spool
; directory will be of the template event-XXXXXX, where XXXXXX is a random
; and unique alphanumeric string.
;
; Default is none, and the events will be dropped on the floor.
;

eventspooldir = /tmp

;
; The alarmreceiver app can either log the events one-at-a-time to individual
; files in the spool directory, or it can store them until the caller
; disconnects and write them all to one file.
;
; The default setting for logindividualevents is no.
;

logindividualevents = no

;
; The timeout for receiving the first DTMF digit is adjustable from 1000 msec.
; to 10000 msec. The default is 2000 msec. Note: if you wish to test the
; receiver by entering digits manually, set this to a reasonable time out
; like 10000 milliseconds.

fdtimeout = 2000

;
; The timeout for receiving subsequent DTMF digits is adjustable from
; 110 msec. to 4000 msec. The default is 200 msec. Note: if you wish to test
; the receiver by entering digits manually, set this to a reasonable time out
; like 4000 milliseconds.
;

sdtimeout = 200

;
; Wait for the connection to settle post-answer. Adjustable from 500 msec. to 10000 msec.
; The default is 1250 msec.
;

answait = 1250

; When logging individual events it may be desirable to skip grouping of metadata

;no_group_meta = yes

;
; The loudness of the ACK and Kissoff tones is adjustable from 100 to 8192.
; The default is 8192. This shouldn't need to be messed with, but is included
; just in case there are problems with signal levels.
;

loudness = 8192

;
; The db-family setting allows the user to capture statistics on the number of
; calls, and the errors the alarm receiver sees. The default is for no
; db-family name to be defined and the database logging to be turned off.
;

;db-family = yourfamily:

;
; End of alarmreceiver.conf
