说明：内线挂断电话后，将外线转到某个IVR的三种实现方法
作者：张拓
2010-11-9
我们有时候需要实现类似这样的功能，即内线挂断电话后，将外线转到某个IVR节点上，让系统去接管这个通道，播放某个提示音、或者其他。
比如服务评分。
客服MM说 "稍后请您为我的服务评分"，然后挂断了电话。这个时候，客户那边就会听到系统录制的评分提示音，如"刚才为您服务的是801，请您为我们的服务打发，灰常满意请按1、满意请按2...."
在asterisk里如何实现呢。
首先，我们看一下内线先挂断电话时，走的哪个拨号规则
-- Executing [s@macro-dial:7] Dial("DAHDI/2-1", "SIP/899||tr") in new stack

-- Executing [h@macro-dial:1] Macro("DAHDI/2-1", "hangupcall") in new stack
-- Executing [s@macro-hangupcall:1] ResetCDR("DAHDI/2-1", "w") in new stack
-- Executing [s@macro-hangupcall:2] NoCDR("DAHDI/2-1", "") in new stack

-- Goto (macro-hangupcall,s,11)
-- Executing [s@macro-hangupcall:11] Hangup("DAHDI/2-1", "") in new stack
== Spawn extension (macro-hangupcall, s, 11) exited non-zero on 'DAHDI/2-1' in macro 'hangupcall'
== Spawn h extension (macro-dial, h, 1) exited non-zero on 'DAHDI/2-1'
== Spawn extension (macro-dial, s, 7) exited non-zero on 'DAHDI/2-1' in macro 'dial'
== Spawn extension (macro-exten-vm, s, 9) exited non-zero on 'DAHDI/2-1' in macro 'exten-vm'
== Spawn extension (from-did-direct, 899, 1) exited non-zero on 'DAHDI/2-1'
-- Hungup 'DAHDI/2-1'
如上图所示、它跑到了 macro-hangupcall的s里
ok，接下来，开始干
第一种方法
1：我们先建立一个拨号规则，编辑extensions_custom.conf文件，加入下面的这些代码
这里，我们让他播放cn目录下面的bangian-hangup提示音："欢迎致电邦建通讯"....
2：内线挂断电话后，将外线转到上面的拨号规则里，编辑extensions.conf文件
如下
[macro-hangupcall]
exten => s,1,ResetCDR(w)
exten => s,n,NoCDR()
; Cleanup any remaining RG flag
;
exten => s,n,GotoIf($[ "x${USE_CONFIRMATION}" = "x" | "x${RINGGROUP_INDEX}" = "x" | "${CHANNEL}" != "${UNIQCHAN}"]?skiprg)
exten => s,n,Noop(Cleaning Up Confirmation Flag: RG/${RINGGROUP_INDEX}/${CHANNEL})
exten => s,n,DBDel(RG/${RINGGROUP_INDEX}/${CHANNEL})
; Cleanup any remaining BLKVM flag
;
exten => s,n(skiprg),GotoIf($[ "x${BLKVM_BASE}" = "x" | "BLKVM/${BLKVM_BASE}/${CHANNEL}" != "${BLKVM_OVERRIDE}" ]?skipblkvm)
exten => s,n,Noop(Cleaning Up Block VM Flag: ${BLKVM_OVERRIDE})
exten => s,n,DBDel(${BLKVM_OVERRIDE})
; Cleanup any remaining FollowMe DND flags
;
exten => s,n(skipblkvm),GotoIf($[ "x${FMGRP}" = "x" | "x${FMUNIQUE}" = "x" | "${CHANNEL}" != "${FMUNIQUE}" ]?theend)
exten => s,n,DBDel(FM/DND/${FMGRP}/${CHANNEL})
exten => s,n(theend),Goto(bangian-hangup,s,1) ;zhangtuo edit,2010-11-9
;exten => s,n(theend),Hangup ;zhangtuo edit,2010-11-9
红色的是改动的地方
3：重新加载拨号规则，使用如下命令
ok，我们测试一下
-- Executing [s@macro-dial:7] Dial("DAHDI/2-1", "SIP/899||tr") in new stack

-- Hungup 'DAHDI/2-1'
上面显示了，挂断电话时，外线已经转到了"bangian-hangup,s,1"里去，外线电话里响起了熟悉的声音"欢迎致电邦建通讯...."
测试成功，上面是手动建立的拨号规则。
那，如果使用现有的IVR、公告、等其它在FreePBX里设置的规则呢
请看下文
第二种方法
1：我们通过FreePBX建立一个IVR节点
如上图所示，该节点名为voip88_ivr,在这个IVR中，它将播放同名的"voip88_ivr.wav"这个系统录音
2:然后我们在extensions_additional.conf里找一下它对应的拨号规则的“context”叫啥
3：编辑extensions.conf文件
如下
[macro-hangupcall]
exten => s,1,ResetCDR(w)
exten => s,n,NoCDR()
; Cleanup any remaining RG flag
;
exten => s,n,GotoIf($[ "x${USE_CONFIRMATION}" = "x" | "x${RINGGROUP_INDEX}" = "x" | "${CHANNEL}" != "${UNIQCHAN}"]?skiprg)
exten => s,n,Noop(Cleaning Up Confirmation Flag: RG/${RINGGROUP_INDEX}/${CHANNEL})
exten => s,n,DBDel(RG/${RINGGROUP_INDEX}/${CHANNEL})
; Cleanup any remaining BLKVM flag
;
exten => s,n(skiprg),GotoIf($[ "x${BLKVM_BASE}" = "x" | "BLKVM/${BLKVM_BASE}/${CHANNEL}" != "${BLKVM_OVERRIDE}" ]?skipblkvm)
exten => s,n,Noop(Cleaning Up Block VM Flag: ${BLKVM_OVERRIDE})
exten => s,n,DBDel(${BLKVM_OVERRIDE})
; Cleanup any remaining FollowMe DND flags
;
exten => s,n(skipblkvm),GotoIf($[ "x${FMGRP}" = "x" | "x${FMUNIQUE}" = "x" | "${CHANNEL}" != "${FMUNIQUE}" ]?theend)
exten => s,n,DBDel(FM/DND/${FMGRP}/${CHANNEL})
;exten => s,n(theend),Goto(bangian-hangup,s,1) ;zhangtuo edit,2010-11-9
exten => s,n(theend),Goto(ivr-22,s,1) ;zhangtuo edit,2010-11-9
;exten => s,n(theend),Hangup ;zhangtuo edit,2010-11-9
4：重新加载拨号规则，使用如下命令

那一刻...
耳边再次响起了熟悉的声音
"欢迎致电邦建通讯....".....
测试成功，前面我们介绍了手动建立拨号规则、通过freepbx建立拨号规则。
如果我们的拨号规则要经常变，比如今天用voip88_ivr ，明天用bangian_ivr
怎么办?
第三种方法
1：我们在freepbx里建立一个"其它应用"，作为统一的入口
如上图所示
我们建立一个名为voip88-huangup的应用，功能键是*6688，这个它的入口，至于电话进入后，将去向何方，可以在"目标"一栏中选择
（这正是我们想要的）
2：编辑extensions.conf文件
如下
[macro-hangupcall]
exten => s,1,ResetCDR(w)
exten => s,n,NoCDR()
; Cleanup any remaining RG flag
;
exten => s,n,GotoIf($[ "x${USE_CONFIRMATION}" = "x" | "x${RINGGROUP_INDEX}" = "x" | "${CHANNEL}" != "${UNIQCHAN}"]?skiprg)
exten => s,n,Noop(Cleaning Up Confirmation Flag: RG/${RINGGROUP_INDEX}/${CHANNEL})
exten => s,n,DBDel(RG/${RINGGROUP_INDEX}/${CHANNEL})
; Cleanup any remaining BLKVM flag
;
exten => s,n(skiprg),GotoIf($[ "x${BLKVM_BASE}" = "x" | "BLKVM/${BLKVM_BASE}/${CHANNEL}" != "${BLKVM_OVERRIDE}" ]?skipblkvm)
exten => s,n,Noop(Cleaning Up Block VM Flag: ${BLKVM_OVERRIDE})
exten => s,n,DBDel(${BLKVM_OVERRIDE})
; Cleanup any remaining FollowMe DND flags
;
exten => s,n(skipblkvm),GotoIf($[ "x${FMGRP}" = "x" | "x${FMUNIQUE}" = "x" | "${CHANNEL}" != "${FMUNIQUE}" ]?theend)
exten => s,n,DBDel(FM/DND/${FMGRP}/${CHANNEL})
;exten => s,n(theend),Goto(bangian-hangup,s,1) ;zhangtuo edit,2010-11-9
;exten => s,n(theend),Goto(ivr-22,s,1) ;zhangtuo edit,2010-11-9
exten => s,n(theend),Goto(from-internal,*6688,1) ;zhangtuo edit,2010-11-9
;exten => s,n(theend),Hangup ;zhangtuo edit,2010-11-9
3：重新加载拨号规则，使用如下命令
ok，我们最后测试一下

总结一下
常言道，工欲善其事，必先找到对应的拨号规则
此例中，拨号规则是 macro-hangupcall
