Cisco Systems OL-14619-01 Alternate MWIs, MWIs for Extensions on a Non-Integrated Phone System

Chapter 6 Integrating Cisco Unity with the Phone System

Optional Integration Features

–A minimum extension length for the extensions entered in the Cisco Unity Assistant. See the Administration—Set the Minimum Length for Subscriber-Defined Alternate Extensions setting.

See the Advanced Settings Tool Help for details on using the settings.

•You can control whether subscribers can use the Cisco Unity Assistant to view the alternate extensions that you specify in the Cisco Unity Administrator. To do so, see the Subscribers > Class of Service > Profile page. The Subscriber-Defined Alternate Extension table displays the alternate extensions that the subscriber adds.

•Neither the Cisco Unity Administrator nor the Cisco Unity Assistant will accept an extension that is already assigned to another subscriber (either as a primary or alternate extension), or to a public distribution list, call handler, directory handler, or interview handler. Cisco Unity verifies that each alternate extension is unique—up to the dialing domain level, if applicable—before allowing either an administrator or a subscriber to create it.

•All alternate extensions use the same transfer settings as the primary extension.

•In many cases, Cisco Unity can activate a message waiting indicator (MWI) for an alternate extension. However, depending on the phones and phone systems involved, some additional phone system programming may be required to set this up.

Alternate MWIs

You can set up Cisco Unity to activate alternate MWIs when you want a new message for a subscriber to activate the MWIs at up to 10 extensions. For example, a message left at extension 1001 can activate the MWIs on extensions 1001 and 1002.

Cisco Unity uses MWIs to alert the subscriber to new voice messages. MWIs are not used to indicate new e-mail, fax, or return receipt messages.

In Cisco Unified Communications Manager integrations, you can also use the alternate MWI feature to activate MWIs on a non-integrated phone system that can send and receive information from Cisco Unity over an RS-232 serial cable.

Setting Up Alternate MWIs for Extensions on the Same Phone System

Cisco Unity can activate alternate MWIs for extensions on the same phone system. Depending on the phones and phone systems, some additional phone system programming may be necessary. Refer to the documentation for the phone system.

MWIs for Extensions on a Non-Integrated Phone System

Cisco Unity can activate MWIs on a phone system that is not integrated with Cisco Unity and that is not part of a two phone system integration (referred to here as a non-integrated phone system). MWI activation requests are sent through an RS-232 serial cable. Calls to subscribers that come from the non-integrated phone system are routed through the gateway to Cisco Unified Communications Manager.

For this method, you must set up:

•A trunk connection between Cisco Unified CM and the non-integrated phone system through a gateway.
