asterisk在正常通话过程中执行拨号计划中动作是通过feature.conf中的[applicationmap ]下定义的，举例如下：
nway-start => *0,callee,Macro,nway-start
nway-zhustart => *0,caller,Macro,nway-zhustart
nway-inv => *7,caller,Macro,nway-ok
nway-noinv => *9,self,Macro,nway-notok
zhugoto-meeting => *5,caller,Macro,zhugoto-meeting
goto-meeting => *5,callee,Macro,goto-meeting
caller和callee 的区别参考：http://blog.csdn.net/radkitty/archive/2009/12/29/5102097.aspx
有些人定义了applicationmap 按键后不能引发制定动作 这是由于未设置DYNAMIC_FEATURES引起的
可以使用DYNAMIC_FEATURES来决定哪些动作可以被执行。
可以在globals_custom.conf中定义DYNAMIC_FEATURES全局变量来使用：
DYNAMIC_FEATURES=nway-start#goto-meeting
也可在拨号计划中通过
exten => s,n,Set(DYNAMIC_FEATURES=nway-zhustart#zhugoto-meeting)
来设置
电话转会议的实现方法请参考我前面的笔记：http://blog.csdn.net/seven407/archive/2010/05/14/5591078.aspx
并附下我最新的实现代码：
extensions.conf 末尾添加：
[default]
;exten => _XXXX,1,Set(DYNAMIC_FEATURES=nway-start#nway-zhustart)
exten => _XXXX,n,Dial(SIP/${EXTEN})
[dynamic-nway]
exten => _XXXXXXXX,1,Answer
exten => _XXXXXXXX,n,Set(CONFNO=${EXTEN})
exten => _XXXXXXXX,n,Set(MEETME_EXIT_CONTEXT=dynamic-nway-invite)
exten => _XXXXXXXX,n,Set(DYNAMIC_FEATURES=)
exten => _XXXXXXXX,n,MeetMe(${CONFNO},1pdMXr)
exten => _XXXXXXXX,n,Hangup()
[dynamic-nway-invite]
exten => 0,1,Read(DEST,dial,,i)
exten => 0,n,Set(DYNAMIC_FEATURES=nway-inv#nway-noinv)
;exten => 0,n,Dial(SIP/${DEST},,g)
exten => 0,n,Dial(Local/${DEST}@from-internal,,g)
exten => 0,n,Set(DYNAMIC_FEATURES=)
exten => 0,n,Gosub(dynamic-nway,${CONFNO},1)
exten => i,1,Goto(dynamic-nway,${CONFNO},1)
[dynamic-nway-dest]
exten => _XXXX,1,Dial(SIP/${EXTEN},,g)
[my-meet-dial]
exten => _XXXXXXXX,1,Read(DEST,dial,,i)
exten => _XXXXXXXX,n,Set(CONFNO=${EXTEN})
exten => _XXXXXXXX,n,Set(DYNAMIC_FEATURES=nway-inv#nway-noinv)
;exten => _XXXXXXXX,n,Dial(SIP/${DEST},,g)
exten => _XXXXXXXX,n,Dial(Local/${DEST}@from-internal,,g)
exten => _XXXXXXXX,n,Set(DYNAMIC_FEATURES=)
exten => _XXXXXXXX,n,Answer
exten => _XXXXXXXX,n,Set(CONFNO=${EXTEN})
exten => _XXXXXXXX,n,Set(MEETME_EXIT_CONTEXT=dynamic-nway-invite)
exten => _XXXXXXXX,n,Set(DYNAMIC_FEATURES=)
exten => _XXXXXXXX,n,MeetMe(${CONFNO},1pdMXr)
exten => _XXXXXXXX,n,Hangup()
[macro-nway-start]
;exten => s,n, SetGlobalVar(MEETMENUM=$[${MEETMENUM} + 1])
;exten => s,1,Set(CONFNO=$[10000 + ${AMPUSER}]);XX
;exten => s,1,Set(CONFNO=$[10000 + ${CALLERID(num)}]);XX
;exten => s,1,Set(CONFNO=10000)
;exten => s,1,Set(CONFNO=$[10000 + ${EXTEN}])
exten => s,1,Set(CONFNO=${STRFTIME(${EPOCH},,%d%H%M%S)})
exten => s,n,ChannelRedirect(${BRIDGEPEER},my-meet-dial,${CONFNO},1)
exten => s,n,Hangup()
exten => s,n,Gosub(dynamic-nway,${CONFNO},1)
[macro-nway-zhustart]
exten => s,1,Set(CONFNO=${STRFTIME(${EPOCH},,%d%H%M%S)})
exten => s,n,ChannelRedirect(${BRIDGEPEER},dynamic-nway,${CONFNO},1)
exten => s,n,Hangup()
exten => s,n,Read(DEST,dial,,i)
exten => s,n,Set(DYNAMIC_FEATURES=nway-inv#nway-noinv)
;exten => s,n,Dial(SIP/${DEST},,g)
exten => s,n,Dial(Local/${DEST}@from-internal,,g)
exten => s,n,Set(DYNAMIC_FEATURES=)
exten => s,n,Gosub(dynamic-nway,${CONFNO},1)
[macro-nway-ok]
exten => s,1,ChannelRedirect(${BRIDGEPEER},dynamic-nway,${CONFNO},1)
[macro-nway-notok]
exten => s,1,SoftHangup(${BRIDGEPEER})
[macro-zhugoto-meeting]
exten => s,1,Set(CONFNO=${STRFTIME(${EPOCH},,%d%H%M%S)})
exten => s,n,ChannelRedirect(${BRIDGEPEER},dynamic-nway,${CONFNO},1)
exten => s,n,Hangup()
exten => s,n,Gosub(dynamic-nway,${CONFNO},1)
[macro-goto-meeting]
exten => s,1,Set(CONFNO=${STRFTIME(${EPOCH},,%d%H%M%S)})
exten => s,n,ChannelRedirect(${BRIDGEPEER},dynamic-nway,${CONFNO},1)
exten => s,n,Hangup()
exten => s,n,Gosub(dynamic-nway,${CONFNO},1)
并修改
[macro-dial]
exten => s,1,GotoIf($["${MOHCLASS}" = ""]?dial)
为
[macro-dial]
exten => s,1,Set(DYNAMIC_FEATURES=nway-zhustart#zhugoto-meeting)
exten => s,n,GotoIf($["${MOHCLASS}" = ""]?dial)
globals_custom.conf中添加：
DYNAMIC_FEATURES=nway-start#goto-meeting
features_applicationmap_custom.conf添加：
nway-start => *0,callee,Macro,nway-start
nway-zhustart => *0,caller,Macro,nway-zhustart
nway-inv => *7,caller,Macro,nway-ok
nway-noinv => *9,self,Macro,nway-notok
zhugoto-meeting => *5,caller,Macro,zhugoto-meeting
goto-meeting => *5,callee,Macro,goto-meeting
