Chapter 1 Planning for Personal Assistant
Intercepting Calls with Personal Assistant
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.
Adding Personal Assistant Without Previously Defined Partitions
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:
1. 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).
2. 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.
