DP: 如何消除瑪凱(IPBB)的惱人的語音提示

    內容表格
    沒有標頭

    瑪凱是國內一家 VOIP Provider,提供 SIP 網路電話服務,不過使用戶在每次撥出時都必須強迫先聽一段語音 "您還可使用xxx分鐘",這樣的設計實在太惱人,比較 make sense 的作法應該是,設計一個特殊碼的撥號,由使用戶主動來查詢自己的通話時間,更人性化的作法,可以在加上"低量通知"功能,由使用戶來設定想要的低量警示值,當低於 xx 通話時間時,系統以 Email 或簡訊通知使用戶。

    既然供應商不願意修改系統,只好自己來作,還好在 Asterisk 上可以有很彈性的作法。從 IPBB 的說法,可以在撥號後再按下 # 鍵就可以略過語音提示,基於這樣的流程,我們就使系統在撥出至 IPBB Trunk 時就自動送一個 # 的 DTMF signal,來模擬手按的動作。

    作法如下,《PBX》《Tools》《File Editor》搜尋 extension《Filter》選擇 extensions_custom.conf

    在 [from-internal-custom] 這段的最下方加上

    include => custom-trunk-out-ipbb  ; Cancel the ipbb's prompted voice, should dial *333+phone number
    

    在所有內容的最底部,加上下方所有內容

    ;;;;;;;;;;;;;;;;;;;;;;;;;; start-ipbb trunk out ;;;;;;;;;;;;;;;;;;;;;;;;;;

    exten => s,1,Wait(1)
    exten => s,2,SendDTMF(#)
    ;;;;;;;;;;;;;;;;;;;;;;;;;; end-ipbb trunk out ;;;;;;;;;;;;;;;;;;;;;;;;;; 

    註:請依你的環境修改第5行

    exten => _*333.,1,Macro(dialout-trunk-dtmf-ipbb,2,${EXTEN:4},,) 

    紅字的數字2 改成實際的 IPBB Trunk 編號
    藍字的部份*333 是撥號的前置碼,如不修改時,撥號方法需為 *333 + 電話號碼; 如撥號時不想要有任何前置碼,可以改為 X.,並且確定 Outbound Route 的撥號規則無衝突情況。

     

    儲存以上修改,但此時這些修改並不會被系統套用,必須執行  CLI 指令 重新載入  Extension 設定,作法如下:

    《PBX》《Tools》《Asterisk Cli》輸入 dialplan reload 《Execute》

    完成。

    如果更改成 X. 的話,必須將後面的 ${EXTEN:4} 改成 ${EXTEN} 哦!
    不然撥號會被吃掉前面四碼
