`ABSTRACT
`(57)
`A process and apparatus to facilitate communication between
`callers and callees in a system comprising a plurality ofnodes
`with which callers and callees are associated is disclosed. In
`
`response to initiation of a call by a calling subscriber, a caller
`identifier and a callee identifier are received. Call classifica-
`tion criteria associated with the caller identifier are used to
`
`classify the call as a public network call or a private network
`call. A routing message identifying an address, on the private
`network, associated with the callee is produced when the call
`is classified as a private network call and a routing message
`identifying a gateway to the public network is produced when
`the call is classified as a public network call.
