Our office has a Toshiba DK40 phone system that was installed about a year ago. We need to update the system settings as far as extensions, greetings, etc. Does anyone know if there is a passcode to enter the system setup for a Toshiba DK40 system. I know there is a universal base password for the norstar systems and wondered if there was one for the Toshiba phone systems. Any assistance is appreciated. Thanks.
