To find out how long the integrity check will take:

Open the Query Manager and select the FaxAction database and type: DBCC CHECKDB.

Check the green arrow or issue a CTL + E and time the check.

WARNING: on larger databases or slow CPUs or busy systems, this will likely degrade performance, so do it after hours (or cancel the operation if your phone starts ringing!)
