Patent

CA 2452146

The present invention provides a method and system for providing media services in Voice over IP telephony. A switch is coupled between one or more audio sources and a network interface controller. The switch can be a packet switch or a cell switch (304). The present invention further provides a method and system for distributed conference bridge processing in Voice over IP telephony. A distributed conference bridge multi-casts mixed audio content of a conference call in a way that reduces replication work at the mixing device. The present invention also provides a method and system for noiselessly switching between independent audio streams. Such noiseless switching preserves valid RTP information at the time of switch over.

La présente invention concerne un procédé et un système permettant la fourniture de services de support dans un système de téléphonie de voix sur IP. Un commutateur est couplé entre une ou des sources audio et un contrôleur d'interface de réseau. Le commutateur peut être un commutateur de paquets ou un commutateur de cellules. L'invention concerne également un procédé et un système pour le traitement par passerelle de conférence répartie dans un système de téléphonie de voix sur IP. Une passerelle de conférence répartie effectue une mutli-diffusion de contenu audio mixte d'une conférence téléphonique de manière à réduire le travail de reproduction au niveau du dispositif de mixage. La présente invention concerne également un procédé et un système permettant la commutation silencieuse entre des flux audio indépendants. Une telle commutation silencieuse préserve l'information de protocole de transport en temps réel au moment de la commutation.
