include more Active directory information
include active directory information in the search.
like location, so if I type a city it will show all the members in that city.
also include the other fields of information from active directory in the contact space, like cell phone numbers

Also show office location and Title or Department in drop down list when transferring a call. You could have 20 Kevin's in an organization and one person answering calls for multiple offices... MANY times the person won't remember the person's last name... the other information would help transfer the call much faster.
