asterisk 中特殊的extension

Special extensions

特殊的extensions
Asterisk makes use of some special extensions, which we will explain now:

Asterisk 使用一些特殊的extensions，解释如下：

  Extension       Description

  

       a       This extension is invoked when a user presses the star key "*" during a

                 voicemail greeting—usually used to allow access to the voicemail system
                 from the outside world

       h       This extension is invoked when a call is hung up

                当一个呼叫挂断的时候，这个exten被调用 

       i        This extension is invoked when the user has asked for an invalid extension
                 number in the context

                 当用户输入错误的时调用这个extension

       o         This extension is called the operator extension and is invoked when the user
                 pressess the zero "0" key from within the voicemail system

       s        This extension is the start extension, primarily used in situations where an
                  inbound call to a context has no information about the extension number
                 that was dialed (usually associated with Macros and Analog (FXO/FXS)
                  interfaces)

                  这个extension是开始的extension（s=start）,主要用在呼入的电话未指定extension的情况下，

                  （通常与宏和模拟接口一起使用）

                 

       t        This extension is invoked upon a user timeout 

                  在用户超时的时候

       T         This extension is invoked upon an AbsoluteTimeout timer expiration

                  

     failed     This extension is invoked when an automatic dial-out feature has failed 
                  当自动外拨失败的时候调用

      fax        This extension is invoked when a Zap (Analog/Digital) channel has detected
                  a fax signal

                  当zap或者dahdi通道检测到传真信号的时候，调用这个extension

      talk       This extension is invoked by the BackgroundDetect application

上面写错了 是 分机 1310 振铃 不是802 笔误

不知楼主试过这个否？我没试成功，若楼主有空，帮忙看下。

AMI 写道

Action: Originate
Channel: Local/1310@from-local
Context: from-local
Exten: 1310
Priority: 1

我用软电话没有试成功，当执行如上 AMI 命令时，首先分机802振铃 接起来之后又会再振铃再接起 它把 “Local/xxx,1” 和 “Local/xxx,2”这两个通道连接接起来了,用的是X-lite3.0免费版。CLI输出完整如下：
