Integration Description
The Siemens 9751 9006i phone system communicates with the Cisco Unity server
by using DTMF sequences. The voice messaging lines from the phone system
connect to the analog voice cards in the Cisco Unity server. Figure 1-1 shows the
required connections.
Figure 1-1 Connections Between the Phone System and Cisco Unity
The phone system sends the following information with forwarded calls:
• The extension of the called party
• The extension of the calling party (for internal calls)
Cisco Unity uses this information to answer the call appropriately. For example,
a call forwarded to Cisco Unity is answered with the personal greeting of the
subscriber. If the phone system routes the call to Cisco Unity without this
information, Cisco Unity answers with the opening greeting.
