Cisco Systems 1.4 Manual De Usuario

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.

When User 1002 calls User 1001, Cisco CallManager uses the calling search space of User 1002, 
cssEmp, and finds the best match to extension 1001 in the NonPAManaged partition. (While cssEmp 
includes the PA partition, and 1XXX in the PA partition is a match for extension 1001, 1001 exists in the 
NonPAManaged partition and is the best match.) The call is sent directly to extension 1001. Because 
Personal Assistant does not intercept the call, no call routing rules are applied.

If you are not already using partitions, then you must create a minimal set in order to implement 
rule-based call routing by using Personal Assistant.

When you have not yet created any partitions or calling search spaces specific to your needs, all of your 
IP phones currently exist by default in the “none” partition in Cisco CallManager. Because the none 
partition exists in all calling search spaces, you can selectively enable Personal Assistant for different 
extensions. If Personal Assistant is not intercepting the dialed number, Cisco CallManager will find the 
number in the none partition, and ring the applicable phone.

You can selectively support Personal Assistant depending on how you assign the partitions and calling 
search spaces. Consider this example:

Create a Personal Assistant partition, for example PA, and a Personal Assistant managed phones 
partition, for example PAManaged. 

Add the interceptor ports (to intercept incoming calls) to the PA partition.

Add the phones of all employees who will use Personal Assistant to the PAManaged partition. 
(Placing these phones in the PAManaged partition effectively removes them from the “none” 
partition.)

Leave all other phones in the “none” partition, including the CTI route point (the pilot port to access 
Personal Assistant) and the media ports (to support Personal Assistant sessions).

Next, create the following calling search spaces:

cssPA—Add the PAManaged partition to it.

cssPhones—Add the PA partition to it.

Note that every calling search space includes the “none” partition by default.
