Integration Description
The Toshiba CTX 670 integration uses a data link, which consists of an RS-232 serial cable connecting
the phone system and the Cisco Unity server. The voice messaging lines from the phone system connect
to the analog voice cards in the Cisco Unity server. Figure 1 shows the required connections.

Call Information
The phone system sends the following information through the data link:
• 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 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.
