Field	Description
Device Name	Enter a name to identify software-based telephones. The
	value can include 1 to 15 characters, including
	alphanumeric, dot, dash, and underscores.
	Cisco CallManager makes this field available only for
	H.323 clients and CTI ports.
Description	Identify the purpose of the device. You can enter the user
	name (such as John Smith) or the phone location (such as
	Lobby) in this field.
	For Cisco VG248 gateways, begin the description with
	VGC<mac address>.
Device Pool	Choose the device pool to which you want this phone
	assigned. The device pool defines sets of common
	characteristics for devices, such as region and date/time
	group.
	The value that you choose overrides the default value for
	this type of device. See the “Device Defaults
	Configuration” section on page 6-1.
Calling Search Space	Choose the appropriate calling search space. A calling
	search space comprises a collection of partitions that are
	searched to determine how a dialed number should be
	routed.
AAR Calling Search	Choose the appropriate calling search space for the
Space	device to use when it performs automated alternate
	routing (AAR). The AAR calling search space specifies
	the collection of route partitions that are searched to
	determine how to route a collected (originating) number
	that is otherwise blocked due to insufficient bandwidth.
