Resolution
As of now, it is not possible to set the enable password/secret for the command line interface (CLI) in the Cisco Unity Express. Even though Cisco Unity Express prompts for an enable password, it is always blank. Based on the Network Infrastructure Considerations for Cisco Unity Express, though there is also an enable mode in the Cisco Unity Express module CLI, Cisco Unity Express has no password capability. Any network administrator with access to enable mode on the router, can access the Cisco Unity Express CLI. There is no user ID or password control on the Cisco Unity Express CLI. Access is controlled through the router. If logging is required, set up the router with AAA/RADIUS monitoring of login access.
