    摘要： The present invention is directed to a method for propagating contextual data in an audio communication by storing the contextual data obtained from a calling party in an extensible mark-up language formatted text document. A telephone call between a first party and a second party is converted to a session initiation protocol based voice over internet protocol communication, and the stored text document is attached to session initiation protocol messages that control the voice over internet protocol communication. The document is attached to the signaling messages by embedding the text document in a session description payload associated with the session initiation protocol message. The attached document is propagated with the audio communication, including when the signaling messages are used to transfer the audio communication from the second party to a third party or to add one or more addition parties to the audio communication.

    摘要： The present invention is directed to a system, including apparatus and architecture, and method for providing scheduled and ad hoc voice over IP conference services having enhanced quality and reliability. The system uses an overlay network of geographically distributed conference servers working simultaneously and collaboratively to host a given conference session. Multiple conference servers simultaneously and collaboratively perform the necessary audio mixing. The voice routing path is established and controlled within the overlay network and supports conference services across different conference service providers.

    摘要： The present invention provides a method and system for providing quality-of-service to VoIP over a wireless local access network by providing periodic, contention-free access to a wireless link for voice packets. This is achieved by coupling Session Initiation Protocol (“SIP”) signaling for call setup with the Point Coordination Function mode of operation of the 802.11 medium access control. The result is that VoIP call signaling via SIP is tied with availability of periodic time-slots on the wireless medium. The periodic time-slots are used to guarantee contention-free access to the wireless link for voice packets. Accordingly, the present invention, in effect, merges two networking technologies: SIP-based VoIP and 802.11-based wireless LANs.
