Asterisk 学习进阶-2

这儿只是把添加的用户配置列出来。

[830]

type=friend ; Friends place calls and receive calls

context=830 ; Context for incoming calls from this user

;secret=blahpoly

host=dynamic ; This peer register with us

;dtmfmode=rfc2833 ; Choices are inband, rfc2833, or info

username=830 ; Username to use in INVITE until peer registers

; Normally you do NOT need to set this parameter

;disallow=all

;allow=ulaw ; dtmfmode=inband only works with ulaw or alaw!

;progressinband=no ; Polycom phones don't work properly with "never"

[808]

type=friend ; Friends place calls and receive calls

context=808 ; Context for incoming calls from this user

;secret=blahpoly

host=dynamic ; This peer register with us

;dtmfmode=rfc2833 ; Choices are inband, rfc2833, or info

username=808 ; Username to use in INVITE until peer registers

; Normally you do NOT need to set this parameter

;disallow=all

;allow=ulaw ; dtmfmode=inband only works with ulaw or alaw!

;progressinband=no ; Polycom phones don't work properly with "never"

主要是定义了一个用户，号码分别为808，830。他们所处的拨号规则段分别为808，830。接着添加拨号规则的段。如下：

[830]

exten => s,1,Wait(1) ; Wait a second, just for fun

exten => s,n,Answer ; Answer the line

exten => s,n,Set(TIMEOUT(digit)=5) ; Set Digit Timeout to 5 seconds

exten => s,n,Set(TIMEOUT(response)=10) ; Set Response Timeout to 10 seconds

exten => s,n(restart),BackGround(demo-congrats) ; Play a congratulatory message

exten => s,n(instruct),BackGround(demo-instruct) ; Play some instructions

exten => s,n,WaitExten ; Wait for an extension to be dialed.

exten => 2,1,BackGround(demo-moreinfo) ; Give some more information.

exten => 2,n,Goto(s,instruct)

exten => 3,1,Set(LANGUAGE()=fr) ; Set language to french

exten => 3,n,Goto(s,restart) ; Start with the congratulations

exten => 1000,1,Goto(default,s,1)

exten => 808,1,Goto(default,s,1)

exten => 500,1,VoicemailMain()

[808]

exten => s,1,Wait(1) ; Wait a second, just for fun

exten => s,n,Answer ; Answer the line

exten => s,n,Set(TIMEOUT(digit)=5) ; Set Digit Timeout to 5 seconds

exten => s,n,Set(TIMEOUT(response)=10) ; Set Response Timeout to 10 seconds

exten => s,n(restart),BackGround(demo-congrats) ; Play a congratulatory message

exten => s,n(instruct),BackGround(demo-instruct) ; Play some instructions

exten => s,n,WaitExten ; Wait for an extension to be dialed.

exten => 2,1,BackGround(demo-moreinfo) ; Give some more information.

exten => 2,n,Goto(s,instruct)

exten => 3,1,Set(LANGUAGE()=fr) ; Set language to french

exten => 3,n,Goto(s,restart) ; Start with the congratulations

exten => 1000,1,Goto(default,s,1)

exten => 600,1,MeetMe(600,i,123456)

exten => 830,1,Voicemail(830@default)

;exten => 830,1,Dial(SIP/830,3)

exten => _[58]30,2,SayDigits(${EXTERN})

exten => 830,102,Playback(priv-recordintro)

exten => 830,103,Playback(spy-h323)

exten => 830,104,Hangup()

为什么拨号规则段加了那么多东西，后面再慢慢解释。其实对于我们简单的通话而言，根本不需要那么多，向下面这样就足够了。

[808]

exten => s,1,Wait(1) ; Wait a second, just for fun

exten => s,n,Answer ; Answer the line

exten => 830,n,Dial(SIP/830,3)

exten => 830,n,Hangup()

只看这些就简洁多了吧，而且基本工作正常，解释一下，客户端（例如800）在sip里面进行了配置，其属于808这个context，故他的所有拨号动作都在808里面进行了定义。当用户呼叫830的时候，他就跳到830这个扩展段，进行拨号。看dial这个函数很清晰，但是他的功能确实强大无比，例如现在我们拨的是sip用户，万一我们需要拨打h323用户怎么办？那就变成dial（h323/**,）,.依此类推，所有的通道都可以采用同样的格式进行定义。

这儿当然也可以制定的复杂一些，例如遇忙时候转语音什么的，在我们的实现中，遇忙跳转到N+101扩展，我们则定义一个忙转的扩展，如下

[808]

exten => s,1,Wait(1) ; Wait a second, just for fun

exten => s,2,Answer ; Answer the line

exten => 830,3,Dial(SIP/830,3)

exten => 830,4,Hangup()

exten => 830,104,Voicemail(830@default)

这样遇忙的时候，则会转移到语音邮件留言，有了上面的基础，你就可以随心所欲进行扩充了，还可以组建会议电话，呼叫等待，更多的功能就留给你进行挖掘了。

下面简单介绍一下语音信箱的配置，语音信箱的配置关键两个文件voicemail.conf和拨号规则文件extensions.conf.

Voicemail.conf 中要增加用于存放语音的邮箱，在asterisk中有专门的语法格式来申明：

Mailbox => password, name, email.

这只是一个最简单的格式，还有很多选项没有列出，如果感兴趣可以参阅相关文档，这里只是给出一个概念。Mailbox是邮箱的编号，通常符合关联设置的扩展号码。后面的password，name和email的意义就比较清晰了。
