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.

The Class of Service Override feature allows you to apply the features of 
your own NBX telephone temporarily to another NBX telephone on the 
same local network.

Example:

■

The telephone in a conference room can be 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). 

To activate the one-call-only Class of Service Override from any NBX 
telephone:

1 Pick up the handset.

2 Press the Feature button and 433.

3 Dial your telephone extension.

4 Dial your voice mailbox password and press #.

5 When you hear the dial tone, you can dial the call in the same way that 

you do from your own NBX telephone.
