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.
