Chapter 4 Internet Subscribers
Internet Subscriber Concepts and Definitions
• When a subscriber leaves the organization or otherwise no longer needs a Cisco Unity account, you
can delete the Internet subscriber account. See the “Deleting Internet Subscribers” section on
page 4-12 for details.
Internet Subscriber Concepts and DefinitionsInternet subscribers are a representation in Cisco Unity of users who do not have mailboxes on the local
Exchange network. Instead, messages for Internet subscribers are sent to an e-mail address that you
specify when you create the Internet subscriber account. The recipient receives voice messages as
e-mails with attached WAV files.
Trusted Internet subscribers are Internet subscribers that are trusted with decrypted secure messages.
Trusted Internet subscribers must be associated with a Trusted Internet Location. Based on the security
settings of the Trusted Internet location, secure messages to Trusted Internet subscribers are decrypted
by the Cisco Unity Voice Connector for Microsoft Exchange before they are sent by the Exchange server.
(Messages to regular Internet subscribers are sent directly by the Exchange server and cannot be
decrypted and therefore cannot be played by the recipient.)
Trusted Internet subscribers are the same as Internet subscribers except the following differences:
• Trusted Internet subscribers are associated with a Trusted Internet location.
• Messages to Trusted Internet subscribers are processed by the Voice Connector.
• Trusted Internet subscribers must have a DTMF extension, whereas extensions are optional for
Internet subscribers.
The concepts discussed in this section apply to both regular Internet subscribers and Trusted Internet
subscribers, except where specifically noted.
Internet subscribers are represented as mail-enabled contacts in Active Directory. You create and manage
Internet subscriber accounts in much the same way that you do regular subscriber accounts. For example,
a subscriber template is used when the Internet subscriber accounts are created, and you can adjust the
call transfer settings for Internet subscriber accounts as needed.
Extensions are optional for Internet subscribers whereas they are mandatory for regular subscribers and
Trusted Internet subscribers. If an Internet subscriber has not been assigned an extension, subscribers
can address messages to that Internet subscriber only in spelled-name mode (if the Internet subscriber
has a voice name). Subscribers can also address messages to Internet subscribers without extensions by
using Cisco Unity ViewMail for Microsoft Outlook or by using the Cisco Unity Inbox.
If you have specified extensions for the Internet subscribers, you can configure the call transfer settings
for the Internet subscribers so that they can be reached by outside callers.
Internet subscribers do not require additional Exchange client access licenses (CALs), and they do not
consume Cisco Unity subscriber licenses. The Cisco Unity subscriber license count does not change
when you create Internet subscribers.
Other than receiving messages (and possibly calls), Internet subscribers do not have access to other
Cisco Unity features, and some sections of the Cisco Unity Administrator are disabled for Internet
subscribers. Internet subscribers:
• Cannot log on to Cisco Unity by phone to check or send messages.
• Cannot log on to Cisco Unity by phone—or use the Cisco Unity Assistant—to adjust personal
settings, so their recorded names and greetings can only be recorded or changed in the Cisco Unity
Administrator.
• Cannot use Cisco Unity ViewMail for Microsoft Outlook or the Cisco Unity Inbox.
