Issue: 檢查 CallPlan RateCard Customer 都正常但仍無法撥出，錯誤訊息如下

[file:Class.A2Billing.php - line:1017 - uniqueid:1336550668.1]:[CallerID:7008374947]:[CN:7008374947]:[ERROR ::> RateEngine didnt succeed to match the dialed number over the ratecard (Please check : id the ratecard is well create ; if the removeInter_Prefix is set according to your prefix in the ratecard ; if you hooked the ratecard to the Call Plan)]

Solution：可能是新增 Rate 時比 Customer 還晚，故造成對應錯誤，重新建一個 Customer 或到該 Customer 再按一次 CONFIRM DATA 試試。

Issue: 新增 Customer 時，出現錯誤: Your new Card hasn't been inserted.

Solution: 依下列順序確認

1. 檢查 /etc/a2billing.conf 的 DB 連線資訊是否正確
2. 可能 DB 有某種異常，執行修復指令
   mysql_fix_privilege_tables --password=<DB root's password>
3. 再不行就修改 /etc/my.cnf
   [mysqld]
   ...
   thread_stack=256K <==加上這行
