Chapter 1 Planning for Personal Assistant

Intercepting Calls with Personal Assistant

Calling Search
Space	Partitions	Assigned To
cssPA	PAManaged	Devices that will not have Personal Assistant evaluate the
	none	called number for interception.
cssPhones	PA	Devices (such as employee IP phones) that can dial internal
	none	and external numbers and access Personal Assistant.

3.Update each IP phone extension that you want managed with the new PAManaged partition and the cssPhones calling search space.

If you do not want to enable Personal Assistant on a particular phone (such as a lobby phone), you can leave the extension assigned to the none partition, but you must update the calling search space.

If you need to update hundreds or thousands of user extensions, consider using the Cisco CallManager Bulk Administration Tool (BAT).

Cisco CallManager				PA Interceptor Port
Setting	User 1001	User 1002	User 1003	Route Point
Phone extension	1001	1002	1003	1XXX
Partition	none	PAManaged	none	PA
Calling search space	cssPhones	cssPhones	cssPhones	cssPA

4.It is important to understand how these changes affect User 1001 and User 1002.

In this example, we have reconfigured the phone of User 1002 to use Personal Assistant by adding it to the PAManaged partition. We have also left the phone of User 1001 in the “none” partition. Finally, we have updated the calling search spaces to search the Personal Assistant partition (PA).

These changes enable the call routing rules of User 1002 to be applied to all incoming calls. To complete the configuration, we have created the 1XXX interceptor port (X matches any digit) in the PA partition so that Personal Assistant will intercept calls to the extension of User 1002.

When User 1001 calls User 1002, Cisco CallManager uses the calling search space of User 1001, cssPhones. Cisco CallManager determines that the best match to extension 1002 within cssPhones is 1XXX, 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 the calls of User 1002 to the phone of User 1003, Cisco CallManager finds the best match to extension 1003 in the “none” partition of the calling search space of Personal Assistant, cssPA, and sends the call directly to User 1003.

Note that because cssPA contains the NonPAManaged partition and does not contain the PA partition, Personal Assistant does not intercept the call a second time to process the active call routing rules of User 1003.
