Set Up Voice Mailbox for Access on Secondary Device

A.

Answer: B. Alternate Extensions

Explanation: In Cisco Unity Connection, alternate extensions allow a voice mailbox to be accessed from a secondary device, such as a mobile phone, home phone, or a hotel phone. Alternate extensions can be set up by the administrator or by the user, depending on the configuration.

To configure alternate extensions for a voice mailbox, the following steps can be followed:

1. Log in to the Cisco Unity Connection Administration interface.
2. Navigate to the user account for which alternate extensions need to be configured.
3. Under the "Alternate Extensions" tab, click the "Add New" button.
4. Select the type of alternate extension from the drop-down list. The available options are:
   • Extension: A phone extension within the same Cisco Unified Communications Manager (CUCM) cluster.
   • Phone Number: A phone number outside the CUCM cluster, such as a mobile phone or a home phone.
   • SIP Address: A SIP address that can be used to reach the mailbox from a SIP-based device.
5. Enter the appropriate information for the selected type of alternate extension.
6. Save the configuration changes.

Once the alternate extensions have been configured, the user can access their mailbox from the secondary device by dialing the appropriate extension or phone number and entering their voicemail PIN. If the user is prompted to enter a mailbox ID or username, they should enter their full email address.

Option A (Attempt Forward routing rule) is used to forward calls to another destination if the call is not answered or if the line is busy. This is not relevant to configuring alternate extensions.

Option C (Alternate Names) allows the administrator to specify additional names for the user that can be used to search for them in the directory. This is not relevant to configuring alternate extensions.

Option D (Mobile User) is used to configure a user's mobile phone as an extension in Cisco Unity Connection. This is a related feature to alternate extensions, but it is not specifically used to set up access to a voice mailbox from a secondary device.
