Asterisk 星号，黑名单号码赢得'；不要挂断

我已经为我的来电实施了一个简单的黑名单。我遇到的问题是，当黑名单者打电话时，我的手机不再响了（这部分很好），但黑名单上的手机没有挂断（这就是问题所在）

extensions.conf中的传入上下文：

exten => 12225551234,1,Zapateller(nocallerid)
same => n,GotoIf(${BLACKLIST()}?hangup)
same => n,Dial(SIP/myphone)
same => n(hangup),Hangup()

将数字添加到黑名单：

CLI> database put blacklist +14445554321 "Blacklisted for testing"

从列入黑名单的14445554321拨打12225551234

通过CLI界面可以看到：

== Using SIP RTP CoS mark 5
 -- Executing [12225551234@from-sipProvider:1] GotoIf("SIP/sipProvider_did9-00000738", "1?hangup") in new stack
 -- Goto (from-sipProvider,12225551234,5)
 -- Executing [12225551234@from-sipProvider:5] Hangup("SIP/sipProvider_did9-00000738", "") in new stack
== Spawn extension (from-sipProvider, 12225551234, 5) exited non-zero on 'SIP/sipProvider_did9-00000738'

这将一直持续到被阻止的呼叫者挂断为止。最后，大约50秒后，如果来电者没有挂断电话，他会听到铃声。我需要挂断他的电话，否则如果他不挂断电话，我将被收取费用。

在挂断电话之前试着接听电话。这就是我使用的：

exten => 12225551234,1,Zapateller(nocallerid)
same => n,GotoIf(${BLACKLIST()}?badlist,s,1)
same => n,Dial(SIP/myphone)
same => n,Hangup()

[badlist]
exten => s,1,Answer
exten => s,n,Wait(1)
exten => s,n,Playback(ss-noservice)
exten => s,n,Hangup
