For complete information about Call Coverage, see Call Coverage in the Cisco Unified
Communications Manager System Guide.
The call forward destination and Calling Search Space field get used to redirect the call to the
forward destination. Specify the following values:
• Voice Mail—Check this check box to use settings in the Voice Mail Profile Configuration
window.
Note When this check box is checked, Cisco Unified Communications Manager ignores the
settings in the Destination box and Calling Search Space. When this check box is
checked for internal calls, the system automatically checks the Voice Mail check box
for external calls. If you do not want external calls to forward to the voice-messaging
system, you must uncheck the Voice Mail check box for external calls.
• Destination—This setting specifies the directory number to which an internal
nonconnected call is forwarded when an application that controls that directory number
fails. Use any dialable phone number, including an outside destination.
Note When you enter a destination value for internal calls, the system automatically copies
this value to the Destination field for external calls. If you want external calls to
forward to a different destination, you must enter a different value in the Destination
field for external calls.
• Calling Search Space—The Forward No Coverage external Calling Search Space is used
to forward the call to the Forward No Coverage external destination. This setting applies
to all devices that are using this directory number.
Note If the system is using partitions and calling search spaces, Cisco recommends that you
configure the forward calling search spaces. When a call is forwarded or redirected to
the call forward destination, the configured call forward calling search space gets used
to forward the call. If the forward calling search space is None, the forward operation
may fail if the system is using partitions and calling search spaces. For example, if you
configure the Forward No Coverage destination, you should also configure the
Forward No Coverage Calling Search Space. If you do not configure the Forward No
Coverage Calling Search Space, and the Forward No Coverage destination is in a
partition, the forward operation may fail.
Note When you choose a Calling Search Space for internal calls, the system automatically
copies this setting to the Calling Search Space setting for external calls. If you want
external calls to forward to a different calling search space, choose a different setting
in the Calling Search Space for external calls.
