An administrator configures the voicemail feature in a Cisco collaboration deployment. The user mailboxes must be configured when the Cisco Unity…

Cisco Unity Connection can automatically create and maintain voicemail mailboxes by synchronizing its user database with Cisco Unified Communications Manager through the AXL SOAP interface. During initial Unity Connection configuration you add one or more “AXL servers”; once enabled, Unity Connection queries CUCM over AXL, imports the CUCM end-users, and immediately provisions voicemail boxes for them. SIP or SCCP integrations only provide call-routing; they do not expose the CUCM user directory. LDAP/Active-Directory synchronization is configured after installation and likewise does not occur “when the Unity Connection server is configured” by the initial wizard. Therefore, configuring an AXL server is the required action.

A. SIP integration supplies call-signaling only; it does not deliver user records for mailbox creation.

B. SCCP integration handles call-control, not directory/user synchronization.

D. LDAP/AD sync is performed post-installation in separate menus; initial server configuration cannot pull users directly from AD for automatic mailbox creation.
