Directory Numbers
Shared Line Appearance

For configuration information, see
Cisco CallManager Administration Guide.
You can set up one or more lines with a shared line appearance. A
Cisco CallManager system considers a directory number to be a shared line if it
appears on more than one device in the same partition. For example, if directory
number 9600 on phone A is in the partition called Dallas and on phone B in the
partition called Texas, then that directory number is not a shared line appearance.
(The directory number 9600 for phone A and phone B must be in the same
partition; for example, Dallas.)
In a shared line appearance, for example, you can set up a shared line, so a
directory number appears on line 1 of a manager phone and also on line 2 of an
assistant phone. Another example of a shared line would be a single incoming 800
number that is set up to appear as line 2 on every sales representative phone in an
office. You can also choose to update a directory number and have the updates
apply to all devices that share the directory number.
The following information provides tips and lists the restrictions for using shared
line appearances with Cisco CallManager:
Shared Line Tips
You create a shared line appearance by assigning the same directory number
•
and partition to different devices.
If other devices share a line, the words Shared Line display in red next to the
•
directory number in the Directory Number Configuration window in
Cisco CallManager Administration.
• If you change the Calling Search Space or Call Forward and Pickup settings
on any device that uses the shared line, the changes apply to all devices that
use that shared line.
To stop sharing a line appearance on a device, change the directory number
•
or partition name for the line and update the directory number in the
Directory Number Configuration window in Cisco CallManager
Administration.
In the case of a shared line appearance, Remove From Device removes the
•
directory number on the current device only and does not affect other devices.
