`
`ABSTRACT
`
`A communication utility for establishing real-time, point-to-
`point communications between processes over a computer
`network includes apparatus for querying a server as to the
`network protocol address of another client process, and
`apparatus for directly establishing a communication link
`with the client process upon receipt of the network protocol
`address from the server. In one embodiment,
`the utility
`includes a sophisticated user interface having features simi-
`Iar to typical telephony hardware but implementing greater
`flexibility with software.
