asterisk feature applicationmap 的caller和callee 的区别

?

? ? ?经过测试，在applicationmap 中定义应用程序的类型为caller或callee，其实为传送那个通道的变量到application：

以下是相关的测试过程，通过对比，大家应该清楚是定义为caller或者是callee：（asterisk 1.2 版本）

?

dialplan 的定义如下：

【test】

exten => _4780,1,Noop
exten => _4780,n,set(mid=${UNIQUEID})
exten => _4780,n,set(LANGID=1)
exten => _4780,n,set(DYNAMIC_FEATURES=test)
exten => _4780,n,dial(SIP/3003,60,Tt)
exten => _4780,n,hangup

?

[macro-IVRS]
exten => s,1,Noop()

exten => s,n,Noop(${UNIQUEID})
exten => s,n,Noop(${BRIDGEPEER})
exten => s,n,NOOP(set(ouid=${mid}))

?

feature.conf

test?=> *0,callee,Macro,IVRS

?

以下分别进行测试：

概况：

????? feature 定义为caller 时，即把输入feature 键方的通道变量传递到feature application 中，即把自己通道的变量传递到application 中,并且按feature 方将会被转入到feature 定义的应用中。

定义为callee是则把feature 键的对方通道的变量传递到feature 的application中，即传送对方通道的变量到application，并把对方引入到feature 定义的应用中。

?

例子：

假如定义了feature键** ，按了** 后将会听到beep 提示声音，分机8001 呼叫8002，并且在8002 分机上输入了**，那么

1.feature定义为caller 时，在8002上会听到beep 声音

2.feature定义为callee时，在8001上会听到beep声音

?

如果是在8001分机上按** 时，则效果为：

?

?

1.feature定义为caller 时，在8001上会听到beep 声音

2.feature定义为callee时，在8002上会听到beep声音
