A utility for enabling real-time, point-to-point communications over computer networks between users having dynamically assigned Internet Protocol addresses includes the ability to identify incoming communications, and, based on the identity of the incoming communication, selectively responding. In one embodiment, an information profile contained within an incoming signal is compared to a plurality of information profiles contained within the personal directory of a user, and, if a match occurs, the notification signal associated with the matched profile is generated. In an alternative embodiment, the information profile contained within the incoming communication includes an identifier of a notification signal which is used to select from a number of predefined notification signals resident within the user's private directory.

Method and apparatus for providing caller identification based responses in a computer telephony environment

A point-to-point Internet protocol exchanges Internet Protocol (IP) addresses between processing units to establish a point-to-point communication link between the processing units through the Internet. A first point-to-point Internet protocol includes the steps of (a) storing in a database a respective IP address of a set of processing units that have an on-line status with respect to the Internet; (b) transmitting a query from a first processing unit to a connection server to determine the on-line status of a second processing unit; and (c) retrieving the IP address of the second unit from the database using the connection server, in response to the determination of a positive on-line status of the second processing unit, for establishing a point-to-point communication link between the first and second processing units through the Internet. A second point-to-point Internet protocol includes the steps of (a) transmitting an E-mail signal, including a first IP address, from a first processing unit; (b) processing the E-mail signal through the Internet to deliver the E-mail signal to a second processing unit; and (c) transmitting a second IP address to the first processing unit for establishing a point-to-point communication link between the first and second processing units through the Internet.

Establishing an internet telephone call using e-mail

A point-to-point Internet protocol exchanges Internet Protocol (IP) addresses between processing units to establish a point-to-point communication link between the processing units through the Internet. A first point-to-point Internet protocol includes the steps of (a) storing in a database a respective IP address of a set of processing units that have an on-line status with respect to the Internet; (b) transmitting a.query from a first processing unit to a connection server to determine the on-line status of a second processing unit; and (c) retrieving the IP address of the second unit from the database using the connection server, in response to the determination of a positive on-line status of the second processing unit, for establishing a point-to-point communication link between the first and second processing units through the Internet. A second point-to-point Internet protocol includes the steps of (a) transmitting an E-mail signal, including a first IP address, from a first processing unit; (b) processing the E-mail signal through the Internet to deliver the E-mail signal to a second processing unit; and (c) transmitting a second IP address to the first processing unit for establishing a point-to-point communication link between the first and second processing units through the Internet.

Establishing a point-to-point internet communication

A communication protocol for establishing real-time, point-to-point communications between client processes over a computer network includes a directory server apparatus for providing current dynamically assigned Internet Protocol addresses of client process currently connected to the computer network. The client processes can be Internet telephony applications each capable of performing a plurality of predefined functions. In accordance with one aspect of the invention, each client process is required to connect to the server apparatus upon initialization and receives a feature definition identifying which of the plurality of functions the client process is authorized to perform. In another aspect of the invention a callee client process verifies the identity of a caller client process with the directory server and is provided with the feature definition of the caller process to prevent the caller client process from communicating with the callee client process in unauthorized manners. In accordance with yet another aspect of the invention, the feature definition is definable by either the requesting client process or the server.

Method and apparatus for dynamically defining data communication utilities

A communication protocol for establishing real-time, point-to-point communications between computer users over a computer network includes a directory server apparatus for providing the current dynamically assigned Internet Protocol addresses of client processes currently connected to the computer network. The server maintains a list of entries, each entry including the Internet Protocol address of a user currently connected to the network. In response to identification of one of the entries by a requesting client process, the server provides the corresponding Internet Protocol address of the entry to the requesting client process. In accordance with a second aspect of the present invention, the directory server monitors the status of client processes connected to the network via periodic notification from the client processes. The server dynamically modifies the time interval at which client processes notify the server, depending on the demand for server resources.

Directory server for providing dynamically assigned network protocol addresses

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 similar to typical telephony hardware but implementing greater flexibility with software.
