一個(gè)簡(jiǎn)單的Asterisk自動(dòng)話務(wù)臺(tái)例子這是一個(gè)簡(jiǎn)單的Asterisk自動(dòng)話務(wù)臺(tái)的例子。我是根據(jù)Asterisk: The Definitive Guide中例子改寫(xiě)的。如有什么疑問(wèn)，請(qǐng)給我郵件：。相互討論，共同進(jìn)步。這個(gè)文檔只是介紹簡(jiǎn)單的話務(wù)臺(tái)的制作過(guò)程，一些細(xì)節(jié)，由于時(shí)間有限，并沒(méi)有詳細(xì)介紹，請(qǐng)勿見(jiàn)怪。1. 創(chuàng)建菜單首先要設(shè)定好菜單的流程，包括：2. 創(chuàng)建對(duì)應(yīng)的語(yǔ)音文件首先要?jiǎng)?chuàng)建對(duì)應(yīng)的語(yǔ)音文件。語(yǔ)音文件的格式是：16bit單聲道，8000Hz的WAV文件。我使用Audacity 2.0.2來(lái)直接錄制這一格式的語(yǔ)音文件。Audacity是一個(gè)免費(fèi)的軟件，下載地址是：/我是通過(guò)360軟件管家找到這個(gè)軟件的。這個(gè)軟件可以錄音，選擇錄音片段，導(dǎo)出相應(yīng)文件。錄音前要選好單聲道和采樣頻率。按照上面說(shuō)的，錄制下面語(yǔ)音文件：Sample promptFilename歡迎來(lái)到中國(guó)銀行。daygreeting.wav歡迎來(lái)到中國(guó)銀行，我們下班了。nightgreeting.wav如果你知道你需要撥打的分機(jī)，請(qǐng)直接輸入。銷(xiāo)售部，請(qǐng)撥1；服務(wù)支持請(qǐng)撥2，公司目錄，請(qǐng)撥井號(hào)；公司地址和傳真，請(qǐng)撥3；重復(fù)當(dāng)前選項(xiàng)，請(qǐng)撥9；等待或撥0轉(zhuǎn)人工。mainmenu.wav我們?cè)跒槟戕D(zhuǎn)接到銷(xiāo)售組，請(qǐng)不要掛機(jī)。holdwhileweconnect.wav我們?cè)跒槟戕D(zhuǎn)接到支持組，請(qǐng)不要掛機(jī)。holdwhileweconnect_support.wav我們的地址是：廣州市天河區(qū)天河北路中信大廈28樓。我們的傳真機(jī)號(hào)碼faxandaddress.wav轉(zhuǎn)人工，請(qǐng)稍候。transfertoreception.wav不能解讀你的輸入信息，請(qǐng)重試。invalid.wav把做好的文件保存到/var/lib/asterisk/sounds/aa目錄中，具體如下：rootkernel aa# ls /var/lib/asterisk/sounds/aa/daygreeting.wav invalid.wavfaxandaddress.wav mainmenu.wavholdwhileweconnect_support.wav nightgreeting.wavholdwhileweconnect.wav transfertoreception.wav3. 創(chuàng)建撥號(hào)規(guī)則我把SIP創(chuàng)建的帳號(hào)的context都指定到j(luò)luotest，當(dāng)撥打1000號(hào)的時(shí)候進(jìn)入main_menu。進(jìn)入main_menu后，首先會(huì)執(zhí)行s開(kāi)頭的撥號(hào)規(guī)則，這樣就會(huì)播出歡迎辭和主菜單內(nèi)容。歡迎辭會(huì)根據(jù)時(shí)間不同而不同。generalstatic=yeswriteprotect=noautofallthrough=yesclearglobalvars=noextenpatternmatchnew=noglobalsCONSOLE = Console/dspIAXINFO = guestTRUNK = DAHDI/G2TRUNKMSD = 1FEATURES =DIALOPTIONS =RINGTIME = 20FOLLOWMEOPTIONS =PAGING_HEADER = Intercommain_menuexten = #,1,Verbose(1, Caller $CALLERID(all) is entering the directory)exten = #,2,Directory(default)exten = 0,1,Verbose(1, Caller $CALLERID(all) is calling the operator)exten = 0,2,Dial(SIP/2134)exten = 1,1,Verbose(1, Caller $CALLERID(all) has entered the sales queue)exten = 1,2,Playback(aa/holdwhileweconnect)exten = 1,3,Queue(jluo)exten = 2,1,Verbose(1, Caller $CALLERID(all) has entered the service queue)exten = 2,2,Playback(aa/holdwhileweconnect_support)exten = 2,3,Queue(jluo)exten = 3,1,Verbose(1, Caller $CALLERID(all) has requested address and fax info)exten = 3,2,Playback(aa/faxandaddress)exten = 3,3,Goto(s,menuprompt)exten = i,1,Verbose(1, Caller $CALLERID(all) has entered an invalid selection)exten = i,2,Playback(invalid)exten = i,3,Goto(s,menuprompt)exten = s,1,Verbose(1, Caller $CALLERID(all) has entered the auto attendant)exten = s,2,Answer()exten = s,3,Set(TIMEOUT(digit)=10)exten = s,4,Wait(1)exten = s,5,GotoIfTime(9:00-17:00,mon-fri,*,*?daygreeting:afterhoursgreeting)exten = s,6(afterhoursgreeting),Background(aa/nightgreeting)exten = s,7,Goto(menuprompt)exten = s,8(daygreeting),Background(aa/daygreeting)exten = s,9,Goto(menuprompt)exten = s,10(menuprompt),Background(aa/mainmenu)exten = s,11,WaitExten(4)exten = s,12,Goto(0,1)exten = t,1,Verbose(1, Caller $CALLERID(all) has timed out)exten = t,2,Goto(0,1)exten = _2XXX,1,Verbose(1,Call $CALLERID(all) to an extension starting with 1)exten = _2XXX,2,Dial(SIP/$EXTEN)jluotestexten = 1000,1,Goto(main_menu,s,1)exten = 123,1,Answer()exten = 123,2,Playback(aa/mainmenu)exten = 123,4,Wait(4)exten = 123,5,Hangup()exten = 200,1,Answer()exten = 200,2,Playback(hello-world)exten = 200,3,Hangup()exten = 201,1,Answer()exten = 201,2,Set(MagicNumber=42)exten = 201,3,SayNumber($MagicNumber)exten = 201,4,Waite(3)exten = 201,5,Hangup()exten = 202,1,Answer()exten = 202,2,SayDigits($EXTEN:1)exten = 203,1,Meetme(1234)exten = 2133,hint,SIP/2133exten = 500,1,AGI(hello-world.sh)exten = 6000,1,Queue(jluo)exten = _2XXX,1,Dial(SIP/$EXTEN)exten = _2XXX,2,Hangup()4. 隊(duì)列配置在上面的撥號(hào)規(guī)則中，使用到了隊(duì)列。Asterisk可以定義出若干條隊(duì)列，每條隊(duì)列中有若干個(gè)成員。撥號(hào)規(guī)則可以使用Queue應(yīng)用來(lái)?yè)艽蜿?duì)列，隊(duì)列自動(dòng)選擇空閑的用戶，建立一個(gè)通道，實(shí)現(xiàn)語(yǔ)音通信。相關(guān)的配置文件如下：rootkernel # vi /etc/asterisk/queues.confjluomember = SIP/2134musicclass = defaultannounce = custom/test上面內(nèi)容只是文件中的一個(gè)節(jié)選，主要是把SIP帳號(hào)2134加入到隊(duì)列中?？梢愿鶕?jù)實(shí)際情況加入實(shí)際的用戶信息。2134需要在sip.conf中配置。5. Sip.conf的配置。SIP帳號(hào)是我使用sip.conf例子模板做了一點(diǎn)修改創(chuàng)建出來(lái)的帳號(hào)。大概修改如下：my-codecs(!); a template for my preferred codecs; disallow=allallow = ulawallow = ilbcallow = g729allow = gsmallow = g723; Or, more simply:;allow=!all,ilbc,g729,gsm,g723,ulawulaw-phone(!); and another one for ulaw-only;disallow=allallow = ulawallow = ilbcallow = g729allow = gsmallow = g723; Again, more simply:;allow=!all,ulawjluo(!)context = jluotest
