hey guys are you willing to help a little here,,,,,

i want to create a voice lab at my home,,,i have 2801 router installed cme 8.5,,,,i didn't get unity express to attach with cme.
what i got only is CUCM Business edition,,,,and installed on vmware player,,,,I am just starting to go on with the help of reference books,,,,so i don't have much idea about how these tools works on together. what i want is i need to go through configuring phones via cme and want to go further for voice mail,,message forward,,,so on there's what i need unity express. but since i don't have unity express,,, can i do all the configuration on cme and just for voice mail or rest of the funtion of unity express does cucm support for the router via laptop?

or cucm wants to rule alone? will you make a little clear about it, please,,,,
