1：进入System Recordings，上传wav语音文件。语音文件必须是音频采样为16位。音频采样级别8kHz。使用PCM编码。
2：进入freepbx IVR模块，建立菜单
3：对入特殊设置可以加入customer-app。自定义的app。这样可以满足需求。
1.2 一个IVR实例1.2.1 IVR实例描述拨打进入号61302350进入XX公司，首先播放欢迎进入公司录音。然后提示：
1：按1进入销售座席队列
2：按2进入技术支持座席队列
3：按任意分机号直接拨打
4：获得公司通讯录按#
1.2.2 实例脚本实现1：配置拨打呼叫号进行IVR。
exten => 61302350,1,Goto(ivr-2,s,1)
2：配置ivr-2 context
[ivr-2]
include => ivr-2-custom
include => ext-findmefollow
include => ext-local
include => app-directory
exten => #,1,dbDel(${BLKVM_OVERRIDE})
exten => #,n,Set(__NODEST=)
exten => #,n,Goto(app-directory,#,1)
exten => h,1,Hangup
exten => s,1,Set(LOOPCOUNT=0)
exten => s,n,Set(__DIR-CONTEXT=)
exten => s,n,Set(_IVR_CONTEXT_${CONTEXT}=${IVR_CONTEXT})
exten => s,n,Set(_IVR_CONTEXT=${CONTEXT})
exten => s,n,GotoIf($["${CDR(disposition)}" = "ANSWERED"]?begin)
exten => s,n,Answer
exten => s,n,Wait(1)
exten => s,n(begin),Set(TIMEOUT(digit)=3)
exten => s,n,Set(TIMEOUT(response)=10)
exten => s,n,Background(custom/qqtech2)
exten => s,n,WaitExten(,)
exten => hang,1,Playback(vm-goodbye)
exten => hang,n,Hangup
exten => 1,1,dbDel(${BLKVM_OVERRIDE})
exten => 1,n,Set(__NODEST=)
exten => 1,n,agi(agi://218.16.124.234/queue.agi?extern=7707499&timeout=10&retry=3&sayDig=1)
exten => 2,1,dbDel(${BLKVM_OVERRIDE})
exten => 2,n,Set(__NODEST=)
exten => 1,n,agi(agi://218.16.124.234/queue.agi?extern=7707499&timeout=10&retry=3&sayDig=1)
exten => 3,1,dbDel(${BLKVM_OVERRIDE})
exten => 3,n,Set(__NODEST=)
exten => 4,n,GotoIf($["x${IVR_CONTEXT_${CONTEXT}}" = "x"]?from-did-direct,200,1:${IVR_CONTEXT_${CONTEXT}},return,1)
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-2,s,begin)
exten => return,1,Set(_IVR_CONTEXT=${CONTEXT})
exten => return,n,Set(_IVR_CONTEXT_${CONTEXT}=${IVR_CONTEXT_${CONTEXT}})
exten => return,n,Goto(ivr-2,s,begin)
exten => fax,1,Goto(ext-fax,in_fax,1)
1.3 IVR同第三方APP联合编程1.3.1 IVR配置FastAgi如果在IVR中需要第三方App支持，这是最常见的实现方法。如有一个实例，
1：请输入用户名并以#号结束(用户输入)
2：请输入密码并以#号结束(用户输入)
3：核对用户名和密码
4：返回结果
实现原理：当输入用户名和密码后，把用户名和密码做为一个临时变量保存。用户名和密码很明显同asterisk无关，需要交给第三方APP处理。设置我们的FastAgi服务器为127.0.0.1。发送出类似的命令:
agi(agi://127.0.0.1/checkpasswd.agi?username=${username}&password=${password}
当AGI接收到此请求时，处理。并把外理结果存储到变量当中，返回。伪代码如下：
String username = agirequest.getParamer(“username”);
String password= agirequest.getParamer(“password”);
Int result =checkUser(username,password);
agiChannle.SerVar(“CHECKRESULT”,result);
if(result==-1)//用户不存在
{
agiChannle.StreamFile(“user is not exist”);
}else if(result==2){//密码不正确
agiChannle.StreamFile(“password is not right”);
}
return;
脚本通过 ${ CHECKRESULT }来查看返回值，进行相应的处理
1.3.2 在通话中触发IVR有时需要在第三方APP中触发IVR。如在通话过程中需要对方输入用户名和密码。实例如下：
1：在通话过程中，座席按1，向对方播放语音提示对方输入用户名和密码
2：进入 IVR配置FastAgi 中的实例
3：如果核对正确，回来继续通话
实现原理
在通话过程中，要响应对方的输入，需要调用waitExtern命令。
实现伪代码：
int result = agiChannel.Dial();//拨号
if(result==-1)
{
int result = agiChannel.sendCmd(ivr-4,1)
}
进入ivr-4，当前通话不断，ivr-4中等待用户输入，ivr-4中伪脚本.
[ivr-4]
include => ivr-4-custom
include => ext-findmefollow
include => ext-local
include => app-directory
exten => h,1,Hangup
exten => s,1,Set(LOOPCOUNT=0)
exten => s,n,Set(__DIR-CONTEXT=default)
exten => s,n,Set(_IVR_CONTEXT_${CONTEXT}=${IVR_CONTEXT})
exten => s,n,Set(_IVR_CONTEXT=${CONTEXT})
exten => s,n,GotoIf($["${CDR(disposition)}" = "ANSWERED"]?begin)
exten => s,n(begin),Set(TIMEOUT(digit)=3)
exten => s,n,Set(TIMEOUT(response)=10)
exten => s,n,WaitExten(,)
exten => hang,1,Playback(vm-goodbye)
exten => hang,n,Hangup
exten => 1,1,dbDel(${BLKVM_OVERRIDE})
exten => 1,n,Set(__NODEST=)
exten => 1,n,Goto(from-did-direct,3001,1)
exten => 2,1,dbDel(${BLKVM_OVERRIDE})
exten => 2,n,Set(__NODEST=)
exten => 2,n,Goto(from-did-direct,3009,1)
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-3,s,begin)
exten => return,1,Set(_IVR_CONTEXT=${CONTEXT})
exten => return,n,Set(_IVR_CONTEXT_${CONTEXT}=${IVR_CONTEXT_${CONTEXT}})
exten => return,n,Goto(ivr-3,s,begin)
exten => fax,1,Goto(ext-fax,in_fax,1)
