Chapter 42 Cisco IP Phone Configuration

Configuring Directory Numbers

Table 42-3 Directory Number Configuration Settings (continued)

Field	Description
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.
