Abstract: A method and apparatus of communicating over a data network includes providing a user interface in a control system for call control and to display information relating to a call session. The control system communicates one or more control messages (e.g., Session Initiation Protocol or SIP messages) over the data network to establish a call session with a remote device in response to receipt of a request through the user interface. One or more commands are transmitted to a voice device associated with the control system to establish the call session between the voice device and the remote device over the data network. A Real-Time Protocol (RTP) link may be established between the voice device and the remote device.

Abstract: A distribution of location information in IP networks by intelligent endpoints is presented. The network comprises an intelligent endpoint operably coupled to a plurality of clients. A first one of the clients registers with the intelligent endpoint that stores location information of the first client. A second one of the clients may also register with the intelligent endpoint that stores the location information of the second client. The intelligent endpoint automatically presents the location information of the first client to the second client and of the second client to the first client. The first client can then directly communicate with the second client. Either client can also be an intelligent endpoint.

Abstract: A method and apparatus in a communications system for providing advanced Internet Protocol (IP) telephony services in an intelligent endpoint. The apparatus and method of the present invention provides a user with the capability to update a local directory from a directory server, perform click to call functions, and perform intelligent processing of incoming calls.
