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

Employee All employee IP phones
