OK, got an STS that was installed about 6 months ago and the database was pulled from an existing installed phone system and uplaoded to this system (quickly finding i messed this up OR that doesn't work right. Prolly the first option.)
The customer called and said that the stations in the classrooms can make calls when they are not supposed to be able to dial out at all, just intercom.
How can set this?

Change the class of service (flash 50, page B, buttons 2 and 3) to 6. That will make them intercom-only.
