CFA CSS Activation Policy Service Parameter
Ensure the CFA CSS Activation Policy service parameter that displays in the Clusterwide
Parameters (Feature - Forward) section of the Service Parameter Configur ation wi ndow is set
correctly for call forward all to work as intended. The parameter includes two possible v alues:
• With Configured CSS (default)
• With Activating Device/Line CSS
When the Calling Search Space Activation Policy is set to Use System Default, the value of
the CFA CSS Activation Policy service parameter gets used to determine the Call F orward All
CSS.
When the option With Configured CSS is selected, the primary and secondary CFA Calling
Search Space get used. When the option With Activating Device/Line CSS is selected, the
primary and secondary CFA Calling Search Space get updated with primary line Cal ling
Search Space and activating Device Calling Search Space.
By default, the value of the CFA CSS Activation Policy service parameter is set to With
Configured CSS.
See Service Parameters Configuration for information on accessing and configuring service
parameters.
Roaming
When a device is roaming in the same device mobility group, Cisco Unified Commun ications
Manager uses the Device Mobility CSS to reach the local gateway. If a user sets Call Forward
All at the phone, the CFA CSS is set to None, and the CFA CSS Activation Policy is set to
With Activating Device/Line CSS, then:
• The Device CSS and Line CSS get used as the CFA CSS when the device is in its home
location.
• If the device is roaming within the same device mobility group, the Device Mobility CSS
from the Roaming Device Pool and the Line CSS get used as the CFA CSS.
• If the device is roaming within a different dev ice mobility gr oup, the De vice CSS and L ine
CSS get used as the CFA CSS.
