  • Patent number: 10171514
    Abstract: A method for routing media calls over a real time packet switch connection includes providing a session controller for connecting to a network. The method further includes providing a signaling switch for connecting to the session controller. The method further includes controlling call routing in the network with the session controller where the call routing control includes identifiers for elements in at least two layers of a seven layer model. The call routing control includes a preference for a codec for the call. The call routing is carried out taking into consideration a mean opinion score qualifier from previous calls having a same source and destination.

  • Patent number: 10171513
    Abstract: A session controller coupled to a database and configured to receive an indication associated with an ingress call is disclosed. The disclosed session controller is further configured to compare at least one of a network capacity, a call-peer bandwidth, or a number of active call-legs associated with the ingress call session against a respective threshold, and to reject the ingress call when a respective threshold is exceeded.

  • Patent number: 9871829
    Abstract: A voice over Internet protocol communication system and method provides infrastructure components as intermediaries between networks, the components include multi-protocol session controllers and a multi-protocol signaling switch as well as a management system. The session controllers process calls and participate in the calls that flow through it. The session controllers process calls that are either at the edge of the network or at the core of the voice over Internet protocol network. The session controllers associate calls with one another in call peers for incoming calls as ingress call peers and for outgoing calls as egress call peers. A centralized database of call routing policies is provided to the session controllers. The session controllers provide cost management, topology hiding, and inter-working, or conversion, of calls from SIP networks to H.323 networks for both voice and video.

  • Patent number: 8755371
    Abstract: A method for multistage routing of packets using call templates is disclosed. An ingress call is filtered based on a plurality of ingress-call parameter values. A parameter value for the ingress call is modified based on a plurality of ingress-call-peer parameter values. A filtered ingress-call parameter value and at least one filtered ingress-call-peer parameter value from a plurality of ingress-call-peer parameter values are converted to an egress-call parameter value and an egress-call-peer parameter value, respectively. An egress call is filtered based on a plurality of egress-call parameter values. A parameter value for the egress call is modified based on a plurality of egress-call-peer parameter values.

  • Patent number: 8547962
    Abstract: A session controller configured to be coupled to a communications network is disclosed. The session controller is configured to receive an indication of a Voice over Internet Protocol (VoIP) registration request at a first time from an endpoint having a third-party registration, and to receive a signaling message from the endpoint at a second time later than the first time. The session controller is further configured to forward an indication of the VoIP registration request and a signaling message to an application server, such that at least a portion of the topology of the communications network beyond the session controller is hidden to the endpoint.

  • Patent number: 8509218
    Abstract: A method includes receiving, at a session controller, session data from a session-detail record. The session data is associated with at least a portion of a call over a Session over Internet Protocol (SoIP) network. A priority indicator associated with an Internet Protocol (IP) packet transmitted over the call is modified at the session controller based on the session data. The priority indicator indicates a priority to transmit the IP packet.

  • Patent number: 8259706
    Abstract: A method includes receiving, at a first endpoint, session data associated with a first Internet Protocol (IP) packet. The IP packet is associated with a session within a Session over Internet Protocol (SoIP) network and the session is associated with a call. An instruction, based on the session data, is sent from the first endpoint to a second endpoint. The instruction is configured to trigger the second endpoint to modify a priority indicator associated with at least one of the first IP packet or a second IP packet associated with the call.

  • Patent number: 8254265
    Abstract: A session controller configured to receive a data packet from a packet-switched network having multiple communication links is disclosed. The disclosed session controller is further configured to define a call-routing policy based on layer-five information, layer-two information, layer-three information and layer-seven information from the data packet. The call-routing policy is configured to define a least-cost routing (LCR) call route for an ingress call over at least one of the plurality of communication links. The LCR call route is associated with an operational cost that is lower than an operational cost associated with at least one other call route over at least one communication link from the plurality of communication links. The session controller is also configured to associate the ingress call to an egress-call peer based on the call routing policy.

  • Patent number: 8204043
    Abstract: A method includes receiving a first media-content packet associated with a first session within a Session over Internet Protocol (SoIP) network. The first media-content packet is associated with a quality-of-service parameter. A transmission priority value associated with the first media-content packet is identified based on a value of the quality-of-service parameter. A priority indicator associated with the first media-content packet and/or a second media-content packet is modified based on the transmission priority value. The priority indicator indicates a priority to transmit the first media-content packet and/or the second media-content packet over a connection within the first session and/or a connection within a second session.
