Asterisk 拨号计划之简单IVR

功能需求，流程转到IVR后，按1 转到外线手机，按2 转到发送短信的AGI，超时后循环播放IVR 3次后挂机

[ivr]

exten => s,1,Set(LOOPCOUNT=0)

exten => s,n(begin),Set(TIMEOUT(digit)=3)

exten => s,n,Set(TIMEOUT(response)=8)

exten => s,n,Background(custom/welcome) ;需要准备welcome提示音

exten => s,n,WaitExten(4)

exten => hang,1,Playback(vm-goodbye)

exten => hang,n,Hangup

exten => i,1,Playback(invalid)

exten => i,n,Goto(loop,1)

exten => t,1,Goto(loop,1)

exten => loop,1,Set(LOOPCOUNT=$[${LOOPCOUNT} + 1])

exten => loop,n,GotoIf($[${LOOPCOUNT} > 2]?hang,1)

exten => loop,n,Goto(ivr,s,begin)

;下面是按键操作

exten => 1,1,Noop(=====call mobile phone===)

exten => 1,n,Goto(from-internal,15813705853,1) ;手机号需要换成目标手机号，另外需要设置freepbx中继

exten => 2,1,Noop(=====exec AGI to send SMS===)

exten => 2,n,AGI(sendSMS.php) ;需要自己写sendSMS.php脚本，并放到agi-bin/中，而且可能需要传递参数到脚本
