It is not necessary for the customer to download and install a large plug-in stand-alone software application or to have third-party software (e.g., Microsoft Netmeeting®) already installed and configured to conduct voice communication over the network 110. Furthermore, if the customer and the agent choose not to employ the voice capability, their respective computers 102 and 104 are not burdened by the unnecessary use of system resources by a voice over Internet protocol application. Those skilled in the art will recognize the advantages over the prior art of the system and method described herein.
  • the advantageous features include the availability to a customer of instantaneous VoIP communication through use of thin applets executing within a web browser, without the requirement of installing large, resource intensive software applications and without the requirement of computer system reconfiguration, plus the separation of the VoIP capability from the text capability thereby avoiding unnecessary system resource usage.

Abstract

L'invention concerne un procédé et un dispositif de communication sur Internet. Dans un mode de réalisation classique, un utilisateur (102) active ce système de communication en enfonçant une touche d'appel ou en activant cette touche par un autre moyen. Ladite touche d'appel est un applet intégré dans une page Web. Cet applet interagit avec un composant de serveur résidant sur un ordinateur serveur (106) de façon à établir une communication entre l'utilisateur et un agent (104). Des communications non vocales sont acheminées par l'intermédiaire de l'ordinateur serveur (106) et deviennent instantanément accessibles entre l'abonné (102) et les agents (104). Dans le cas d'une communication de type biunivoque, des communications vocales passent entre l'utilisateur (102) et l'agent (104) directement d'égal à égal. Pour une communication de type co-univoque, des communications vocales sont acheminées par l'intermédiaire de l'ordinateur serveur (106).
