重新載入設定

# asterisk -rx "dialplan reload"

// 操作流程

1. 主持人及參加人員使用任何一支分機撥 9991。
2. 系統提示：請輸入會議室編號，手機輸入任一組編號，例如 111555。
3. 系統提示：會議室XXXX開始錄音。
4. 進入會議室並開始會議通話。

Notes:

＊ 啟動會議室功能的簡碼 9991，可以修改成其他號碼。
＊ 會議室編號不須事先做設定，第一位成員進入會議室後即完成會議室的開設。
＊ 同個會議室的所有成員必須輸入相同的會議室編號。
＊ 啟動/關閉會議錄音，可以修改 FLAGS 變數，將 i 刪除表示關閉錄音功能。
＊ 錄音檔儲存位置，在 /var/spool/asterisk/monitor，檔名為 conferenceNO.-Timestamp。

安裝 Asterikast

// 安裝 Perl 模組

perl -MCPAN -e shell
capn> install Math::Round
capn> install File::Touch 
cpan> reload
cpan> quit

// Create DB and importing the data

mysql -u root -p
mysql> CREATE DATABASE conference;
mysql> GRANT ALL PRIVILEGES ON conference.* TO asteriskuser@localhost;
mysql> exit
cd /usr/src/appkonference/asterikast/
cd sql/
mysql -u root -p conference < asterikastConferenceManager.db 

修正 Table 的錯誤

mysql -u root -p conference
mysql> ALTER TABLE conference ADD uniqueid VARCHAR(32);
