The server appliance is preinstalled with an operating system and the Cisco Unified CallManager 5.0 application. It is fully operational upon startup, requiring entry of just a few configuration items such as IP address and domain.
Like said in earlier post, appliances comes with the OS and software build pre-loaded (still you have to run the wizard to setup and go through atleast 30-45 minutes of setup time). It looks exactly like regular MCS servers. The price of appliance = price of server + price of callmanager software. You also have the option to buy servers and software ala-carte. The reason this option is there because, if you want to purchase a HP or IBM server of your own (this may be a cheaper option, compared to buying a Cisco MCS server), then all you need to buy from Cisco is the software for Callmanager.
The keyword bundle in the Cisco world has the same literal meaning as the word itself. A group of software or hardware or both clubbed together which may be profitable to purchase as a bundle, compared to buying the individual components ala-carte.
Unity atleast as of today dont have an appliance model, not sure if there will be any in the future.
