Chapter 42 Cisco IP Phone Configuration
Configuring Directory Numbers
Calling Search Space Choose the calling search space to use when forwarding
to the specified destination.
You can configure calling search space for Forward All,
Forward Busy, Forward No Answer, and Forward on
Failure directory numbers. The value you choose applies
to all devices using this directory number.
If you set the Forward All Calling Search Space field to
<none>, Cisco CallManager uses the calling search
spaces of the line and the phone when the user forwards
calls using the Cisco IP Phone User Options panes or the
CFwdAll softkey on the phone. If you want to restrict
users from forwarding calls on their phones, you must
choose a restrictive calling search space from the
Forward All Calling Search Space field; for example:
You have two calling search spaces: Building and PSTN.
The Buiding calling search space only allows users to
call within the building, while the PSTN calling search
space allows users to call within and outside the building.
You assign the phone to the PSTN calling search space
and the line on your phone to the Building calling search
space. If you set the Call Forward All calling search
space to <none>, the Cisco CallManager can forward
calls to any number within the PSTN or building calling
search spaces. To prevent the user from forwarding calls
to numbers outside the building, set the Call Forward All
calling search space to Building.
Display Enter the text that you want to appear on the called party
phone when a call is placed from this line; typically, use
the user name or the directory number. You can enter up
to 30 alphanumeric characters.
Leave this field blank to display the extension.
The value you enter applies only to the current device.
