Chapter 64 Directory Number Configuration
Directory Number Configuration Settings
Forward on CTI Failure This field applies only to CTI route points and CTI ports. The settings in this row specify the
forwarding treatment for external calls to this CTI route point or CTI port if the CTI route
point or CTI port fails. 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.
• 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.
• Calling Search Space—This setting applies to all devices that are using this directory
number.
Forward Unregistered
Internal
This field applies to unregistered internal DN calls. The calls are rerouted to a specified
Destination Number or Voice Mail.
Note You must also specify the maximum number of forwards in the Service Parameters
Configuration window for a Directory Number. See the
“Service Parameters
Configuration” section on page 25-1.
Forward Unregistered
External
This field applies to unregistered external DN calls. The calls are rerouted to a specified
Destination Number or Voice Mail.
Note You must also specify the maximum number of forwards in the Service Parameters
Configuration window for a Directory Number. See the
“Service Parameters
Configuration” section on page 25-1.
No Answer Ring Duration
(seconds)
Used in conjunction with Call Forward No Answer Destination, this field sets the timer for
how long the phone will ring before it gets forwarded. Leave this setting blank to use the value
that is set in the Cisco CallManager service parameter, Forward No Answer Timer.
Caution By default, Cisco Unified Communications Manager makes the time for the T301
timer longer than the No Answer Ring Duration time; if the set time for the T301
timer expires before the set time for the No Answer Ring Duration expires, the call
ends, and no call forwarding can occur. If you choose to do so, you can configure
the time for the No Answer Ring Duration to be greater than the time for the T301
timer. For information on the T301 timer, choose System
> Service Parameters;
choose the server, the Cisco CallManager service, and then the parameter in the
window that displays.
Call Pickup Group Choose the number that can be dialed to answer calls to this directory number (in the specified
partition).
