Chapter 45 Cisco IP Phone Configuration
Configuring Directory Numbers
Table
Field | Description |
|
|
Calling Search Space | Choose the appropriate calling search space. A calling |
| search space comprises a collection of partitions that are |
| searched for numbers that are called from this directory |
| number. The value that you choose applies to all devices |
| that are using this directory number. |
| Note Changes result in an update of the numbers that |
| are listed in the Call Pickup Group field. |
| You can configure calling search space for Forward All, |
| Forward Busy, Forward No Answer, and Forward on |
| Failure directory numbers. The value that you choose |
| applies to all devices that are 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 by using the Cisco IP Phone User Options windows |
| 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 Building 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. |
