Finding Phones With Incorrect CSS

SQL queries can be used to quickly report on common configuration mistakes that build up over time, such as having the wrong CSS on a phone for the device pool it is in, simply plug in the correct values & run the query from the CLI. Using like in the SQL query means that it's also possible to use certain wildcards (e.g. % being zero or more characters) to aid in the search.

SELECT d.name, d.description, dp.name, css.name FROM device AS d INNER JOIN devicepool AS dp ON d.fkdevicepool = dp.pkid INNER JOIN callingsearchspace AS css ON d.fkcallingsearchspace = css.pkid WHERE dp.name LIKE 'DP-Frankfurt-Phones' AND css.name NOT LIKE 'CSS-Frankfurt-Unrestricted' ORDER BY d.name

The output will include the device name, device description, device pool name and CSS name:

admin:run sql SELECT d.name, d.description, dp.name, css.name FROM device AS d INNER JOIN devicepool AS dp ON d.fkdevicepool = dp.pkid INNER JOIN callingsearchspace AS css ON d.fkcallingsearchspace = css.pkid WHERE dp.name LIKE 'DP-Frankfurt-Phones' AND css.name NOT LIKE 'CSS-Frankfurt-Unrestricted' ORDER BY d.name
name            description     name        name
