Chapter 1 Planning for Personal Assistant
Intercepting Calls with Personal Assistant
3. Create the calling search space for Personal Assistant, in this example, cssPA, and add the partitions
indicated in the following table to it.
4. Change the partition of User 1002 to PAManaged (see the “Why You Need a Partition for
Personal Assistant Managed Phones” section on page 1-22 for a complete explanation of this task)
With Pers onal Assistant now added to this example, you can understand how user calls are intercepted.
When User 1001 calls User 1002, Cisco CallManager uses the calling search space of User 1001,
cssEmp. Cisco CallManager determines that the best match to extension 1002 within the cssEmp is
1XXX (where X matches any digit), which exists in the PA partition. Therefore, Cisco CallManager
routes the call to Personal Assistant instead of sending it to the phone of User 1002. Personal Assistant
processes the active call routing rules of User 1002 and uses the applicable rule. If no rule applies, the
call goes directly to the extension of User 1002, because the calling search space of Personal Assistant,
cssPA, contains the partition PAManaged, which is the partition in which the extension of User 1002
exists. If the applicable rule instructs Personal Assistant to transfer User 1002 calls to the phone of User
1003, Cisco CallManager finds the best match to extension 1003 in the NonPAManaged partition of the
calling search space of Personal Assistant, cssPA, and sends the call directly to User 1003.
