A number of organisations have been hit by problems relating to Security by Default introduced with the UCM 8.x. An overview of Security by Default and how to Manage ITL files can be found here: Security by Default and Managing ITL Files
If it is nessesary to delete the ITL file from a number of IP Phones, this video shows you how to manage ITL Files remotely using PhoneView from Unified FX - (http://www.unifiedfx.com)
