Configuration FAQ

1. Q. How can I avoid matching short caller ids?

A. You can use a condition in the WHERE clause to ensure that only caller ids of sufficient length are matched. This is useful if your database contains company phone numbers with similar prefixes, but when receiving calls the caller id is set to the shorter main phone number of the company.

select destination from callerid_table where calleridnum like '%[NUMBER]' and length('[NUMBER]') > 4

2. Q. How can I match data in my database when sometimes the callerid arrives with an international prefix of + country codes, other times 00 country code and other times just as a national number?

A. You may use the MySQL TRIM function to adjust the presented caller id to match the type of data in your database. For example:

select destination from callerid_table where calleridnum like concat('%',TRIM(LEADING '+' FROM TRIM(LEADING '0' FROM '[NUMBER]')))
