3Com V7000 IP Phone User Manual


 
Making Calls 31
For example, suppose a company has three offices:
Phones at the Chicago office use an extension range from 1000
through 1999.
Phones at the Atlanta office use an extension range from 2000
through 2999.
Phones at the Dallas office use an extension range from 3000 through
3999.
In this example, to call a user in Dallas, a user in Chicago dials a Dallas
extension (3000 through 3999). The dial plan on the Chicago VCX system
sets up the necessary connection to the Dallas VCX system and then to
the extension at that site.
Class of Service
Override
The Class of Service Override feature allows you to apply the capabilities
of your own VCX telephone temporarily to another VCX telephone on
the same local network.
For example, the telephone in a conference room may be configured to
prevent long-distance telephone calls. You may, however, need to place a
long-distance call during a meeting. If the permissions included with the
Class of Service on your phone allow long-distance calling, you can use
the Class of Service Override feature to apply your phone features to the
conference room phone for one call only.
To activate the one-call-only Class of Service Override for a Manager’s
phone:
1 Press the Features soft button.
2 Scroll to the COS Override feature.
3 Press the Select soft button. The display panel displays COS Override
on for a few seconds
.
4 Enter the COS number (your phone extension) and press #.
5 Enter the COS password (your telephone password) and press #.
6 When you hear the dial tone, dial the destination telephone number.
When you use Class of Service (CoS) Override, any reports that are
generated on the VCX system indicate that the CoS features of your own
VCX telephone were applied temporarily to the telephone on which you
made the call.
