The Unified Communications Module can host the following applications:

Linux
This is the base operating system used. However, no specific Linux knowledge is required for installation and maintenance.

Management Services
This is a shell version of IP Office that allows basic configuration of services such as remote SSL VPN connections for server support. It also controls security settings for access to the server's menus. It does not support call features such as users, extensions or trunks.

one-X Portal for IP Office
This is a web browser based application that users can use to control making and answering calls on their phone. It also provides a range of gadgets for the user to access features such as their directory, call log and voicemail messages. The one-X Portal for IP Office application is configured and managed remotely via web browser.  

Voicemail Pro
This is a voicemail server. It provides mailbox services to all users and hunt groups on the IP Office system. In addition, you can customize it to provide a range of call routing and voicemail services. Maintainers use the Windows Voicemail Pro client, downloadable from the server, to remotely configure the service.

Web Manager
You can configure and manage the server via browser access to the Web Manager menus. The menus also allow the launching of other clients used to configure and monitor the services run by the server.

Optional Services
The Unified Communications Module does not support any optional services (for example Media Manager, WebRTC Gateway or Web Client).
