First Claim
1. A voice over Internet protocol (VOIP) system for supporting real time communications for both pulse code modulation (PCM), telephone networks and Internet protocol (IP) telephone packet networks in an enterprise including in combination:
- a directory of PCM and IP addresses in an enterprise including a translation address database for members of the enterprise having IP terminals, addresses for IP telephones with Internet connectivity, and addresses of other VOIP gateways on the Internet;
a VOIP gateway linked with the directory and connected to receive requests from both PCM and IP telephones, the VOIP gateway providing voice prompts and responses to calling party requests in the form of either DTMF digits or voice signals; and
the VOIP gateway further operating in response to calling party approval to automatically process a link between the calling party and a called party using a translated address assigned in the directory translation address database to the called party.

Abstract
A voice over Internet protocol (VOIP) directory service for communications users of an enterprise locates a telephone or work station of a called party for the purpose of setting up real-time communication, either from a pulse code modulation (PCM) telephone or from an Internet protocol (IP) telephone, or a computer by way of the world wide web, using a common directory database. Once the directory entry has been found, it may be immediately called through use of translated addresses assigned to the selected called party device.
