Class of Service Override
81
Class of Service 
Override
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 telephones in your organization’s conference rooms are 
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 activate the one-call-only Class of Service Override from any NBX 
telephone:
Pick up the handset.
Press the Feature button and 433.
Dial your telephone extension.
Dial your voice mailbox password and press #.
When you hear the dial tone, you can dial the call in the same way that 
you do from your own NBX telephone.
When you use Class of Service (CoS) Override, any reports that are 
generated on the NBX system indicate that the CoS features of your own 
NBX telephone were applied temporarily to the telephone on which you 
made the call.
