Which of the following fields are mandatory when you complete the VoiceMailUserTemplate? (Choose two.)

Explanation:
The Alias field and the Extension field are mandatory fields in the VoiceMailUserTemplate when you manually create a new user with a voice mailbox in Cisco Unity Connection Administration. Cisco Unity Connection can integrate with various phone systems, including Cisco Unified Communications Manager (UCM). The Alias field holds the key that the Unity Connection database uses to identify a user; therefore, the Alias value must always be unique. The Extension field is used to link a UCM user to a Unity Connection mailbox; therefore, it is important that the Unity Connection user have an extension that matches the extension defined for the corresponding user in UCM. If the extension does not match, some of the Unity Connection integration features will not work correctly. For example, if you changed the extension for a user in UCM and did not make the corresponding change for the user in Unity Connection, the user could receive new voice mail in his or her mailbox but might not receive new voice message notifications on his or her IP phone.

The Alternate Extension field is not mandatory in the VoiceMailUserTemplate when you manually create a new user with a voice mailbox in Cisco Unity Connection Administration, because the Alternate Extension field is not available in the VoiceMailUserTemplate. The Alternate Extension field is typically used in Cisco Unity Connection Administration to enable a single voice mailbox to serve more than one directory number (dn). For example, up to nine administrator-configured alternate extensions, or lines, can be assigned to a single voice mailbox. These alternate extensions can be individual dns from the voice virtual LAN (VLAN) or the numbers of external devices. As a result, it is possible to enable a user to conveniently access Unity Connection from a mobile phone or from another IP phone. Similarly, an Alternate Extension can be used to access a single voice mailbox from multiple line appearances on a single IP phone. However, you can only add alternate extensions by editing a single user’s account or by editing users in Bulk Edit mode.

Neither the DisplayName field nor the Employee ID field is mandatory in the VoiceMailUserTemplate when you manually create a new user with a voice mailbox in Cisco Unity Connection Administration.
