Cisco Unity is designed to leverage the features of Microsoft Exchange
server and third-party enterprise fax messaging solutions to create a powerful
universal inbox, which provides single-point access to voicemail, email, and
faxmail. Subscribers are able to receive notification when a new fax arrives
and request delivery of fax and email messages to a fax machine.

There must be an Exchange gateway or connector component that
facilitates communication between the fax server and Microsoft Exchange.
The fax messages must arrive in the subscriber's inbox with a
distinct message class, such as IPM.Note.Fax.
Clients must be able to send outbound fax messages using this
addressing format: [FAX:name@number].
Note: Installing fax software on the Cisco Unity server is not supported.
Cisco Unity doesn't interact directly with the fax server; Unity
interacts with Exchange. Therefore, the fax server must also interact with
Exchange by using an Exchange gateway/connector component. This is the
component that directs inbound fax messages to the subscriber's inbox and
directs outbound faxmail to the fax server.
When the fax gateway delivers a new fax message to a subscriber, it
must arrive in the Exchange inbox with a message class that can be
distinguished from a generic email message. This allows Cisco Unity to identify
the message as a fax and act accordingly.
Unity's ability to deliver email and faxmail to a fax machine is
dependent on the fax gateway's ability to recognize outbound messages with the
[FAX:name@number] format. Cisco Unity sends the message in this format, at
which point the fax server should route it to a fax port for delivery to a fax
