Abstract

The user of a local computer node (i.e., a caller) selects a remote computer node (i.e., a callee) for a computer conference call from a display containing a directory of possible callees. In one embodiment, the directory is an alphabetical combination of a network list maintained by a network administrator and a personal list for the caller. The user of the caller can access and edit the personal list, but only access the network list. When displayed to the user, the possible callees from the personal list are distinguishable from the possible callees from the network list.
