  • Patent number: 7583660
    Abstract: A method and apparatus for enabling a user to signal to the network that a call to be initiated or a call that is in progress needs to occur in a peer-to-peer relationship with the terminating endpoint. The network will then remove itself from the call signaling and media path and direct the signaling and media communication to occur directly between the two endpoints.

  • Publication number: 20070286161
    Abstract: A method and apparatus for enabling a peering arrangement between distinct packet networks so that traffic between these networks remains on the IP network from the point of origination to the point of termination are disclosed. IP peering is an arrangement that allows two or more IP carriers to be interconnected so that IP packets originating in one carrier can be terminated in another carrier's network. In one embodiment, the peering arrangement between packet networks is implemented while establishing a class of service across different packet networks.

  • Patent number: 7468984
    Abstract: The present invention enables network providers to create peering arrangements with other providers that allow them to fail over to other networks in the event of a site failure. This invention would lower the cost to provide site diversity within a provider's network by allowing cost sharing between the provider's network and other networks. For example, when an Application Server (AS) in a network fails, the network provider can send a call to a partner's network and uses an AS in the partner's network to process the call request.

  • Patent number: 8184548
    Abstract: A method and apparatus for integrating billing of usage of multiple applications onto a single bill are disclosed. For example, in a single day, a user may download musical selections, watch on demand video sessions, and make numerous phone calls. All the sessions can be activated over a single video endpoint device and through a single network service. Records of these sessions can be generated and aggregated to produce a single billing statement that can be accessed on a near real time basis by the user and paid automatically or at a scheduled time.

  • Patent number: 7599359
    Abstract: The present invention enables edge components, such as Border Elements, of the service provider's network to capture performance data on all endpoints connected to them including registered devices (e.g., CPE gateways, IP phones, and terminal adaptors) and access links. The present invention enables the performance data to be sent to a centralized repository that consolidates information across the entire network, analyzes it, and segments it with respect to location of events that cause defects in calls. The performance data can then be graphically mapped into predefined network segmentations to enable faster identification and resolution of network problems.

  • Patent number: 8064452
    Abstract: A method and apparatus for enabling calls destined for a terminating point on a packet network, e.g., a VoIP network, that is experiencing a service disruption to be forwarded by the network to another endpoint is disclosed. The method enables subscribers to register an alternative number, such as a cell phone number, a relative's phone number, or a work number, that the network can use to forward calls in the event of a service disruption. In one embodiment, the provider can even use an alternative transport network, such as the PSTN, to forward these calls until the VoIP network service is restored.

  • Patent number: 8867524
    Abstract: A method and apparatus for enabling service providers to support video services by creating a display frame, such as a picture-in-picture display frame, on an active video display device, such as a television (TV), when an incoming call is received are disclosed. The calling party identification and the service logic to manipulate the call are displayed within the display frame. The network can provide service logic functions such as, but are not limited to, answering the call, sending to call to voice mailbox, providing a busy tone to the calling party, and forwarding the call to another SoIP endpoint.

  • Patent number: 7664106
    Abstract: A method and apparatus for providing emergency services, e.g., E911 services, for nomadic users by utilizing network announcements to remind customers to update location information used to provide services on packet networks, such as Voice over Internet Protocol (VoIP) and Service over Internet Protocol (SoIP) networks, are disclosed. For example, the method enables the VoIP or SoIP service provider to detect a change in the IP address associated with either the broadband modem or the router through which a terminal adaptor is used to access services when a customer is logging on from a new location. In turn, the method sends a reminder network announcement message to the terminal adaptor, e.g., to be played when the terminal adaptor goes off-hook.

  • Patent number: 8411668
    Abstract: A method and apparatus for enabling providers of PSTN toll free services to stagger simultaneous transmission of call setup signaling messages into an IP based teleconference bridge, supported by a VoIP network, by suspending a subset of calls and placing them on hold while placing other calls to be connected to the conference bridge are disclosed. The PSTN network can stagger calls by limiting the number of call setup signaling messages to be sent to the VoIP network within a predefined period of time interval and spread all the calls over multiple of such predefined periods. Prerecorded announcements or music can be played while the calls that have been placed on hold are in queue.

  • Patent number: 7715412
    Abstract: A decomposed H.323 border element is disclosed that is useful for providing an entry point from one or more H.323-based networks into a SIP-based VoIP network. In one embodiment, the signaling element of the BE is separated into a separate functional entity from the media control element to facilitate a single signaling entity controlling multiple media entities. In another embodiment, the security element of the border element is also separated from the media control element so that firewall and network address translation elements may be performed by a separate functional entity. In a further embodiment, the media transcoding element is separated from the media control element. In a final embodiment, the internetworking facility between the SIP and H.323 element is separate from the H.323 gatekeeper elements.
