Limiting What Users Can Do With the System
You can limit what you allow users to do with the system by configuring the 
following:
❑ Maximum time in call — Go to System Info > Admin Setup > General Setup 
and specify the maximum call length allowed.
❑ Allow Dialing — You can prevent users from making calls to destinations 
other than those listed in the Address Book. Go to System Info > Admin 
Setup > General Setup and clear the Allow Dialing option. Users can make 
calls from the Address Book but cannot access the Video Phone screen to enter 
other video numbers.
❑ Allow H.320 and H.323 Mixed Calls — If you do not want to allow mixed 
protocol calls on your system, go to System Info > Admin Setup > Video 
Network > Call Preferences, and clear this option. 
❑ Allow Address Book changes — If you do not want users to save changes to 
the local address book of the system, go to System Info > Admin Setup > 
General Setup and clear this option.
❑ Allow Modifications to Camera Presets — If you have set presets on the 
sytem and you do not want users to change or delete them, go to System 
Info > Admin Setup > General Setup and clear this option.
