Asterisk 星号共享变量

我正在尝试在asterisk服务器上的通道之间共享一些变量。我有一个自定义上下文，在其中设置变量并将其发送到本地通道：

exten => _X.,n,Set(SHARED(VAR1,Local/${EXTEN}@from-internal)=${VAR1})
exten => _X.,n,Set(SHARED(VAR2,Local/${EXTEN}@from-internal)=${VAR2})
exten => _X.,n,Set(SHARED(VAR3,Local/${EXTEN}@from-internal)=${VAR3})
exten => _X.,n,Set(SHARED(VAR4,Local/${EXTEN}@from-internal)=${VAR4})
exten => _X.,n,Dial(Local/${EXTEN}@from-internal)

后来我尝试使用这个变量，它们看起来是空的。我试过几个例子：

例1：

exten => s,n,Set(VAR1=${IMPORT(Local/${CALLED_NUMBER}@from-internal-custom,VAR1)})
exten => s,n,Set(VAR2=${IMPORT(Local/${CALLED_NUMBER}@from-internal-custom,VAR2)})
exten => s,n,Set(VAR3=${IMPORT(Local/${CALLED_NUMBER}@from-internal-custom,VAR3)})
exten => s,n,Set(VAR4=${IMPORT(Local/${CALLED_NUMBER}@from-internal-custom,VAR4)})

例2：

exten => s,n,Set(CDR(VAR1)=${SHARED(VAR1,${CHANNEL})})
exten => s,n,Set(CDR(VAR2)=${SHARED(VAR2,${CHANNEL})})
exten => s,n,Set(CDR(VAR3)=${SHARED(VAR3,${CHANNEL})})
exten => s,n,Set(CDR(VAR4)=${SHARED(VAR4,${CHANNEL})})

例3：

exten => s,n,Set(CDR(VAR1)=${SHARED(VAR1)})
exten => s,n,Set(CDR(VAR2)=${SHARED(VAR2)})
exten => s,n,Set(CDR(VAR3)=${SHARED(VAR3)})
exten => s,n,Set(CDR(VAR4)=${SHARED(VAR4)})

什么都不管用

请帮忙！

谢谢大家!

它确实有效。检查你的变量和通道。嗨@arheops，谢谢你的回答。我试图运行core set verbose 4来查看dialplan的执行情况，但仍然没有结果。。你知道我怎么查吗？
