A2B 內建已經有多國語音的IVR，此篇將說明：
- 如何開啟多國語音 IVR 的功能
- 預設並沒有包含中文語音，如何多增加一個語言。
開啟多國語音IVR
啟用步驟：
- 檢查各種語言的語音檔是否已存在目錄 /var/lib/asterisk/sounds/en, es, fr, etc.....。
- 修改 agi-conf#
- play_menulanguage=Yes，預設是 No。
- conf_order_menulang=en:fr:es，選擇語言的順序，以冒號區隔。
目前有支援多國語言的模組：
- 播報餘額提示
- Vocher
增加中文的IVR
- 預錄中文選單的語音檔
- menu_tw.gsm
- num_tw_1.gsm
- 因為系統預設是 en，所以將以上兩個中文話語音檔方在 /var/lib/asterisk/sounds/en
- 新增目錄 /var/lib/asterisk/sounds/tw，將其他中文化的語音檔儲存在這裡。
- 修改 agi-con#
play_menulanguage=Yes
force_language=tw ;如果用戶沒有選擇時
conf_order_menulang=tw:en:fr:es
新增 Admin UI 的語言
