Chapter 42 Cisco IP Phone Configuration
Configuring Directory Numbers
Table
Field | Description |
|
|
Calling Search Space | Choose the calling search space to use when forwarding |
| to the specified destination. |
| You can configure calling search space for Forward All, |
| Forward Busy, Forward No Answer, and Forward on |
| Failure directory numbers. The value you choose applies |
| to all devices 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 using the Cisco IP Phone User Options panes 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 Buiding 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. |
|
|
Display | Enter the text that you want to appear on the called party |
| phone when a call is placed from this line; typically, use |
| the user name or the directory number. You can enter up |
| to 30 alphanumeric characters. |
| Leave this field blank to display the extension. |
| The value you enter applies only to the current device. |
