Chapter 64 Directory Number Configuration Directory Number Configuration Settings
Forward No Answer External The settings in this row of fields specify the forwarding treatment for external calls to this
directory number if the directory number does not answer. 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, the calling search space of the voice mail pilot gets
used. Cisco Unified Communications Manager ignores the settings in the Destination
box and Calling Search Space.
Note 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 indicates the directory number to which an external call is
forwarded when the call is not answered. Use any d ial abl e phone nu mb er, includin g a n
outside destination.
Note When you enter a destination value for internal calls, the syste m 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 Answer external Calling Search Space is used to
forward the call to the Forward No Answer external destination. It applies to all devices
that are using this directory number.
Note If the system is using partitions and calling search space s, Cisc o re commends that yo u
configure the forward calling search spaces. When a call is forwar ded o r redi recte d 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 No ne, the forward operation
may fail if the system is using partitions and calling search spaces. For example, if you
configure the Forward No Answer destination, you should al so c onf i gure th e F orw ard
No Answer Calling Search Space. If you do not configure the Forward No Answer
Calling Search Space, and the Forward No Answer destination is in a partition, the
forward operation may fail.
Note When you choose a Calling Search Space for internal calls, the system automat ica lly
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, you must choose a
different setting in the Calling Search Space drop-down list box for external calls.
