Using Partitions and Calling Search Spaces Without Personal Assistant

To illustrate partitions and calling search spaces, consider this example in which partitions and calling search spaces are used without Personal Assistant:

The following partitions were created to support lobby phones, employee phones, and calls destined for the PSTN.

Partition Name	Designated Devices Assigned to Partition
Lobby	All lobby phones
Employee	All employee IP phones
PSTN	All externally destined route patterns (local PSTN)

The following calling search spaces were created and the partitions were assigned to them to provide different services. For example, to disallow external calls from the lobby phones, the cssLobby calling search space does not include the PSTN partition.

Calling Search Space	Partitions	Assigned To
cssLobby	Employee	Devices (such as lobby IP phones) that can dial only internal
	Lobby	numbers.
cssEmp	Lobby	Devices (such as employee IP phones) that can dial both
	Employee	internal and external numbers.
	PSTN
cssGW	Lobby	PSTN voice gateway used for outside callers to access lobby
	Employee	and employee phones.

The following partitions and calling search spaces were assigned to individual extensions.

Cisco CallManager Setting	User 1001	User 1002	User 3000	User 5555
Phone extension	1001	1002	3000	5555
Partition	Employee	Employee	Lobby	PSTN
Calling search space	cssEmp	cssEmp	cssLobby	cssGW

When User 3000 dials User 1001, Cisco CallManager looks in the calling search space of User 3000, cssLobby. Because cssLobby includes the Employee partition in which the extension of User 1001 exists, the call goes through successfully.

However, if User 3000 dials User 5555, the call cannot be completed, because the cssLobby calling search space does not include the PSTN partition in which the extension of User 5555 exists. Effectively, this means that people using the lobby phone cannot make outside calls.
