Hi RobI've already checked this file locations but there is only the ver. 3.0.3 support included on the 4.2.8 UC500 version. In the 4.2.9 version there is the Unity Express 3.2.1. version.Piertonio

Thanks again !!!I suppose the CLI was the only way...even if during a small course teacher told us we could use either CLI and GUI (and this spunded strange for me)....now I'm sure with your replies I can't do it with GUI.

Thank you for your answer !!!I know this solution..i have to use the cli and with some instructions I can resolve this issue... but I'd like to know id is there a way to do it using the Cisco Configuration Assistant gui....
