  • Patent number: 6917675
    Abstract: To set up a conference call which includes two, three or more participants, when the participating residential gateways (RGs) lack the necessary capability, a call agent designates a capable residential gateway RG, such as an embedded or stand-alone multi-media terminal adapter (eMTA or MTA) or a cable modem voice (CM), to serve as a residential conference mixer (RCM). The call agent routes outbound voice traffic from the participating RGs to the RCM, which mixes the traffic from the RGs participating in the conference call and directs the mixed voice traffic to the participating RGs. The call agent monitors the RGs for information useful to determine availability for conferencing.

  • Patent number: 6856809
    Abstract: A method, computer system, computer program product, and user interface for enabling SMS users to engage in many-to-many conversation, or an SMS conference, utilizing SMS services. Specifically, a user initiates an SMS conference by sending a short message, including the contact numbers for a group of conference participants, to a control center. The control center establishes an SMS conference by storing the contact information as a conference group and assigning a unique identifier to the conference group. Thus, the SMSC establishes an SMS conference by associating the conference group with a unique identifier. The SMSC transmits the short message from the conference initiator to each participant. A participant is able to send a message to all conference participants by addressing the message to the unique identifier. The control center then forwards the message to each participant in the conference as indicated by the unique identifier.

  • Patent number: 6512823
    Abstract: Interacting call appearances are realized by enabling voice input/output to be simultaneously available on any combination of call appearances at a given time on a given terminal. Consequently, a user may, for example, listen to the voice output of one or more call appearances that are active at the terminal at a given time. Additionally, the user may direct voice input to one or more call appearances that are active at the terminal at a given time. Thus, the user, at any given time, may listen or speak to one or more parties on unrelated calls. Additionally, a user can employ more than one voice input/output device at his/her terminal. Specifically, the ability to simultaneously use more than one call appearance at a terminal at a given time is realized by separating call control from media routing and input/output control. Thus, the appearance of a call at a terminal is separated from the voice input/output that is required for the call.
