Finally, to complete integration, you must perform the following tasks:
Manually configure or import Unity subscribers.
In Cisco CUCM Administration, specify a voicemail profile for directory numbers and configure directory numbers to
forward calls to voicemail (the voicemail pilot number) as appropriate (no answer, busy, and so on).
Note that when subscribers are added in Unity, the subscriber phone extension must be specified. It is also possible to specify
additional alternative extensions (often the subscriber's cell phone number). The configuration of these extensions is important to
ensure that Unity is able to route calls to the correct mailbox when someone calls that subscriber's numbers, and to ensure that a
subscriber is able to directly access his mailbox.
When a call is forwarded by CUCM to Unity, the following information is included:
Called party's extension
Calling party's extension or external phone number (assuming that caller ID is available, if the caller calls from an external
phone)
The reason the call was forwarded to Unity (the extension is busy, there is no answer, or the extension is configured to
forward all calls)
So when, for example, someone calls a subscriber's phone and CUCM forwards the call to Unity, Unity can associate the call with the
correct mailbox by matching the Unity subscriber extension to the extension information provided by CUCM.
Similarly, when a subscriber calls Unity, Unity is able to match the caller ID against the Unity subscriber extensions and, assuming
a match, allow direct access to the subscriber's mailbox. If Unity is unable to match the caller ID against a Unity subscriber's
extensions, Unity prompts the caller for his extension number and password (rather than just, perhaps, a password if the caller ID is
recognized).
One of the most common issues with Unity and CUCM integration is with MWI. CUCM will turn on/off the MWI of the phone
corresponding to the calling party number sent by Unity.
