What happens if I am using the default database (SQL Server 2005 Express) and reach its database capacity?
In systems using the “Express” edition, the database size is checked once a day and whenever users log in. If it exceeds 3.7 GB, a warning is displayed; if it exceeds 3.8 GB, an error message is displayed and rating for all switches will be disabled. If you are approaching the 3.8 GB limit, you should create an archive and then delete call records. Alternatively, you can upgrade to the full SQL Server version.
