Dialing a Call to a Remote Office 97
Cancelling an MWI
Message
After you have sent an MWI message, you can cancel it and remove it
from the list on the target telephone. If it is the only unattended MWI
message on the target telephone, cancelling it turns off the MWI light.
You can cancel an MWI message only from the same extension from
which you sent the MWI message.
To cancel an MWI message using a 3Com Manager’s Telephone:
1 Press the Features soft button.
2 Scroll to MWI to Phone Cancel.
3 Press the Select button.
4 Dial the extension to which you sent the MWI message that you want to
cancel and press #.
You can also press the Access Button if one is configured for MWI Cancel
or use Feature + 413.
Dialing a Call to a
Remote Office You can dial calls between sites in your organization that are separated
geographically but that are linked by a Wide Area Network (WAN)
connection. Each site must have an NBX system. Typical configurations
are described in the next sections.
Using Unique
Extensions
In the sample network shown in Figure 5 , everyone in the entire
organization has a unique telephone extension. Whenever you make a
call to an extension that is not located at your own site, your NBX system
sets up a connection to the NBX system at the other extension’s site.
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 NBX system
sets up the necessary connection to the Dallas NBX system and then to
the extension at that site.
