Cisco Unity Express Features
This guide describes the set of Cisco Unity Express CLI commands and tasks for configuring, managing, 
and maintaining Cisco Unity Express applications, such as voice mail. 
This guide complements the GUI administration tasks described in the Cisco Unity Express GUI 
Administrator Guide.
The focus of this guide is the Cisco Unity Express application. It does not provide information on 
installation of Cisco routers, Cisco network modules, Cisco Unified Communications Manager Express 
router., or Cisco Unified Communications Manager server. For more information about those topics, see 
Cisco Unity Express Documentation, By Version.
This chapter contains the following sections:
  • Platforms and Cisco IOS Software Images, page 1
  • Cisco Unity Express Feature List, page 2
Platforms and Cisco IOS Software Images
Cisco Unity Express applications use a set of commands that are similar in structure to Cisco IOS 
software commands. However, Cisco Unity Express commands do not affect the Cisco IOS 
configuration. 
See the Release Notes for Cisco Unity Express for detailed information about the Cisco Unity Express 
hardware and software platforms.
Note We highly recommend attaching an uninterruptible power supply (UPS) to the router housing the 
Cisco
 Unity Express module. Any reliable UPS unit provides continuous power to maintain the 
operation of the router and the Cisco
 Unity Express module. Consider the unit’s capacity and run time 
because power consumption differs among Cisco platforms. Ideally, a UPS should include a signaling 
mechanism that directs the router to shut down Cisco
 Unity Express properly and then powers off the 
router.
Supported Cisco Unified IP Phones
See the Release Notes for Cisco Unity Express 8.6 for details about supported Cisco Unity IP phones.
