Class of Service Override 71
Call Permissions Your administrator establishes Call Permissions to control the types of
calls that can be dialed from your telephone. The administrator can
configure these permissions to change depending on the time of day. For
example, your administrator can prevent long-distance calls from being
dialed from your telephone outside of business hours.
To view your current call permissions, log in to NBX NetSet > User
Information > Call Permissions.
Class of Service
Override
The Class of Service Override feature allows you to apply the features
of your own 3Com Telephone temporarily to another 3Com Telephone
on the same local network.
Example:
■ The telephone in your organization’s conference room is configured so
that long-distance telephone calls cannot be dialed from it. You may,
however, need to place a long-distance call during a meeting. Using
the Class of Service Override feature, you can apply the features of
your own telephone to the conference room telephone for one call
only and dial the call, assuming that your Call Permissions allow you
to make long-distance calls from your own telephone.
If your system uses a messaging application other than NBX Messaging,
use the documentation for your messaging application instead of these
instructions.
To enable the one-call-only Class of Service Override from a 3Com
Manager’s Telephone:
1 Press the Features soft button.
2 Scroll to COS Override.
3 Press Select.
4 Dial your phone extension.
5 Dial your voice mail password and press #.
6 When you hear the dial tone, you can dial the call in the same way that
you do from your own 3Com Telephone.
You can also use the Feature Code 433 to turn Class of Service Override
on.
