Asterisk dialplan applications

Overview

Asterisk dialplan application 내용 정리

NoOp()

Do Nothing (No Operation).

This application does nothing. However, it is useful for debugging purposes.

This method can be used to see the evaluations of variables or functions without having any effect.

Syntax

NoOp([text])

• text - Any text provided can be viewed at the Asterisk CLI.

AddQueueMember(), RemoveQueueMember()

Queue 에 멤버를 추가/삭제 한다. 상담원의 Login/Logout 으로 이해하면 된다.

[QueueMemberFunctions]
exten => *54,1,Verbose(2,Logging In Queue Member)
  smae => n,Set(MemberChannel=${CHANNEL(channeltype)}/${CHANNEL(peername)})
  same => n,AddQueueMember(support,${MemberChannel})
  same => n,Verbose(1,${AQMSTATUS}) ; ADDED, MEMBERALREADY, NOSUCHQUEUE
  smae => n,Playback(agent-loginok)
  same => n,Hangup()

exten => *56,1,Verbose(2,Logging Out Queue Member)
  same => n,Set(MemberChannel=${CHANNEL(channeltype)}/${CHANNEL(peername)})
  same => n,RemoveQueueMember(support,${MemberChannel})
  same => n,Verbose(1,${RQMSTATUS}) ; ADDED, MEMBERALREADY, NOSUCHQUEUE
  same => n,Playback(agent-loggedoff)
  same => n,Hangup()

PauseQueueMember(), UnpauseQueueMember()

해당 멤버를 Pause/Unpause 시킨다. 상담원의 자리비움, 대기중 으로 이해하면 된다. Queue 에서 멤버를 추가/삭제 하지 않고도 가용/비가용 여부를 설정할 수 있다.

exten => *72,1,Verbose(2,Pause Queue Member)
  same => n,Set(MemberChannel=${CHANNEL(channeltype)}/${CHANNEL(peername)})
  same => n,PauseQueueMember(support,${MemberChannel})
  same => n,Verbose(1,${PQMSTATUS}); PAUSED, NOTFOUND
  same => n,Playback(dictate/paused)
  same => n,Hangup()

exten => *87,1,Verbose(2,Unpause Queue Member)
  same => n,Set(MemberChannel=${CHANNEL(channeltype)}/${CHANNEL(peername)})
  same => n,UnpauseQueueMember(support,${MemberChannel})
  same => n,Verbose(1,${UPQMSTATUS}); UNPAUSED, NOTFOUND
  same => n,Playback(agent-loginok)
  same => n,Hangup()

AMD()

This application attempts to detect answering machines at the beginning of outbound calls. Simply call this application after the call has been answered (outbound only, of course).

When loaded, AMD reads amd.conf and uses the parameters specified as default values. Those default values get overwritten when the calling AMD with parameters.

This application sets the following channel variables:

    AMDSTATUS - This is the status of the answering machine detection
        MACHINE
        HUMAN
        NOTSURE
        HANGUP
    AMDCAUSE - Indicates the cause that led to the conclusion
        TOOLONG - Total Time.
        INITIALSILENCE - Silence Duration - Initial Silence.
        HUMAN - Silence Duration - afterGreetingSilence.
        LONGGREETING - Voice Duration - Greeting.
        MAXWORDLENGTH - Word Count - maximum number of words.

Syntax

AMD([initialSilence,[greeting,[afterGreetingSilence,[totalAnalysis Time,[miniumWordLength,[betweenWordSilence,[maximumNumberOfWords,[silenceThreshold,[maximumWordLength]]]]]]]]])

• initialSilence - Is maximum initial silence duration before greeting. If this is exceeded set as MACHINE
• greeting - is the maximum length of a greeting. If this is exceeded set as MACHINE
• afterGreetingSilence - Is the silence after detecting a greeting. If this is exceeded set as HUMAN
• totalAnalysis Time - Is the maximum time allowed for the algorithm to decide HUMAN or MACHINE
• miniumWordLength - Is the minimum duration of Voice considered to be a word
• betweenWordSilence - Is the minimum duration of silence after a word to consider the audio that follows to be a new word
• maximumNumberOfWords - Is the maximum number of words in a greeting. If this is exceeded set as MACHINE
• silenceThreshold - How long do we consider silence
• maximumWordLength - Is the maximum duration of a word to accept. If exceeded set as MACHINE

Queue

In addition to transferring the call, a call may be parked and then picked up by another user.

This application will return to the dialplan if the queue does not exist, or any of the join options cause the caller to not enter the queue.

This application does not automatically answer and should be preceeded by an application such as Answer(), Progress(), or Ringing().

This application sets the following channel variable upon completion:

    QUEUESTATUS - The status of the call as a text string.
        TIMEOUT
        FULL
        JOINEMPTY
        LEAVEEMPTY
        JOINUNAVAIL
        LEAVEUNAVAIL
        CONTINUE

Syntax

Queue(queuename,[options,[URL,[announceoverride,[timeout,[AGI,[macro,[gosub,[rule,[position]]]]]]]]])

• queuename
• options
  • C - Mark all calls as "answered elsewhere" when cancelled.
  • c - Continue in the dialplan if the callee hangs up.
  • d - data-quality (modem) call (minimum delay).
  • F - When the caller hangs up, transfer the called member to the specified destination and start execution at that location.
    • context
    • exten
    • priority
  • F - When the caller hangs up, transfer the called member to the next priority of the current extension and start execution at that location.
  • h - Allow callee to hang up by pressing *.
  • H - Allow caller to hang up by pressing *.
  • n - No retries on the timeout; will exit this application and go to the next step.
  • i - Ignore call forward requests from queue members and do nothing when they are requested.
  • I - Asterisk will ignore any connected line update requests or any redirecting party update requests it may receive on this dial attempt.
  • r - Ring instead of playing MOH. Periodic Announcements are still made, if applicable.
  • R - Ring instead of playing MOH when a member channel is actually ringing.
  • t - Allow the called user to transfer the calling user.
  • T - Allow the calling user to transfer the call.
  • w - Allow the called user to write the conversation to disk via Monitor.
  • W - Allow the calling user to write the conversation to disk via Monitor.
  • k - Allow the called party to enable parking of the call by sending the DTMF sequence defined for call parking in features.conf.
  • K - Allow the calling party to enable parking of the call by sending the DTMF sequence defined for call parking in features.conf.
  • x - Allow the called user to write the conversation to disk via MixMonitor.
  • X - Allow the calling user to write the conversation to disk via MixMonitor.
• URL - URL will be sent to the called party if the channel supports it.
• announceoverride
• timeout - Will cause the queue to fail out after a specified number of seconds, checked between each queues.conf timeout and retry cycle.
• AGI - Will setup an AGI script to be executed on the calling party's channel once they are connected to a queue member.
• macro - Will run a macro on the called party's channel (the queue member) once the parties are connected.
• gosub - Will run a gosub on the called party's channel (the queue member) once the parties are connected.
• rule - Will cause the queue's defaultrule to be overridden by the rule specified.
• position - Attempt to enter the caller into the queue at the numerical position specified. 1 would attempt to enter the caller at the head of the queue, and 3 would attempt to place the caller third in the queue.
