Call Information
The QSIG/DPNSS integration sends the following information with forwarded calls:
•The extension of the called party
•The extension of the calling party (for internal calls) or the phone number of the calling party (if it is an external call and the system uses caller ID)
•The reason for the forward (the extension is busy, does not answer, or is set to forward all calls)
Cisco Unity Connection uses this information to answer the call appropriately. For example, a call forwarded to Cisco Unity Connection is answered with the personal greeting of the user. If the phone system routes the call to Cisco Unity Connection without this information, Cisco Unity Connection answers with the opening greeting.
Integration Features
The QSIG/DPNSS integration with Cisco Unity Connection provides the following features.
Call forward to personal greeting | When an incoming call is routed to an unanswered extension, the |
| call is forwarded to the voice mail of the user. The caller then hears |
| the personal greeting of the user and can leave a message. |
|
|
Call forward to busy greeting | When an incoming call is routed to a busy extension, the call is |
| forwarded to the voice mail of the user. The caller then hears the |
| busy greeting (if the user enabled it) and can leave a message. |
|
|
Caller ID | Cisco Unity Connection receives caller ID information from the |
| phone system (if available). This information appears in the subject |
| line of the message in the desktop messaging application. |
|
|
Easy message access | A user can retrieve messages without entering an ID. Cisco Unity |
| Connection identifies a user based on the extension from which the |
| call originated. A password may be required. |
