User Voice Messaging System Access
Cisco Unified Communications Manager lets you integrate with different voice messaging systems, including the Cisco Unity voice messaging system. Because you can integrate with a variety of systems, you must provide users with information about how to use your specific system.
You should provide this information to each user:
Make sure that you have used Cisco Unified Communications Manager to configure the Messages button on the Cisco Unified IP Phone.
Make sure that you have configured a default voice messaging system password for all users.
Make sure that you have used Cisco Unified Communications Manager to set up a message waiting indicator (MWI) method.
