Calling Search Space Choose the appropriate calling search space. A calling
search space comprises a collection of partitions that are
searched for numbers that are called from this directory
number. The value that you choose applies to all devices
that are using this directory number.
Note Changes result in an update of the numbers that
are listed in the Call Pickup Group field.
You can configure calling search space for Forward All,
Forward Busy, Forward No Answer, and Forward on
Failure directory numbers. The value that you choose
applies to all devices that are using this directory
number.
If you set the Forward All Calling Search Space field to
<none>, Cisco CallManager uses the calling search
spaces of the line and the phone when the user forwards
calls by using the Cisco IP Phone User Options windows
or the CFwdAll softkey on the phone. If you want to
restrict users from forwarding calls on their phones, you
must choose a restrictive calling search space from the
Forward All Calling Search Space field; for example:
You have two calling search spaces: Building and PSTN.
The Building calling search space only allows users to
call within the building, while the PSTN calling search
space allows users to call within and outside the building.
You assign the phone to the PSTN calling search space
and the line on your phone to the Building calling search
space. If you set the Call Forward All calling search
space to <none>, the Cisco CallManager can forward
calls to any number within the PSTN or building calling
search spaces. To prevent the user from forwarding calls
to numbers outside the building, set the Call Forward All
calling search space to Building.
