Creating Multiple User Accounts from Cisco Unified Communications Manager Users
An alternate way to add Cisco Unity Connection voice mail users to the system is to create them by importing Cisco Unified Communications Manager (CM) (formerly known as Cisco Unified CallManager) users.
You use the Tools > Import Users page in Cisco Unity Connection Administration to create multiple user with voice mail accounts from Cisco Unified Communications Manager users. You can also import application users into Connection without a voice mailbox.
Note Cisco Unified Communications Manager users must have a Primary Extension defined or they will not appear on the Tools > Import Users page in Cisco Unity Connection Administration.
When user accounts are created this way, Connection takes the user Alias, Extension, First Name, and Last Name from Cisco Unified CM, and fills in the remaining information from the user template that you specify. Data from the fields that are taken from Cisco Unified CM cannot be modified by using Connection Administration. Instead, the information must be changed in Cisco Unified Communications Manager Administration.
The Synch Users page allows you to manually refresh information from Cisco Unified CM for voice mail users who were created by using the Import Users page.
