說明
A2Billing 預設安裝時是不支援 Voicemail 功能的，本篇將提供在 A2B 新增 Voicemail 功能的教學。
功能目的：當 A2B 使用了 DID 電話轉接服務時，如果電話不通或無人接聽時，Caller 可以自動進入語音信箱作錄音留言。
系統設置
系統環境：
方法一：使用 voicemail.conf
需要修改以下檔案：
- /etc/asterisk/voicemail.conf
- /var/www/html/common/lib/common.defines.php
- /var/www/html/A2Billing_UI/Public/form_data/FG_var_card.inc
voicemail.conf：
[general]
...
...
sendvoicemail=yes ; Allow the user to compose and send a voicemail while inside
; VoiceMailMain() [option 5 from mailbox's advanced menu].
; If set to 'no', option 5 will not be listed.
searchcontexts=yes ; Current default behavior is to search only the default context
; if one is not specified. The older behavior was to search all contexts.
...
[default]
