Abstract: A device receives a Session Initiation Protocol (SIP) response that includes a load header associated with a downstream Session Initiation Protocol (SIP) device. The device also determines an amount of traffic to send to the downstream Session Initiation Protocol (SIP) device based on the load header. The device further sends the determined amount of traffic to the downstream Session Initiation Protocol (SIP) device.

Abstract: Systems for monitoring, storage, and analysis of information in signaling messages, communicated from originating networks to a destination network through one or more intermediate networks are described. Correlation and comparison between signaling messages of interest sent from an origination network to signaling messages received by the destination network allows for the detection of inconsistent information, e.g., information fields in a communicated message that have been altered, either intentionally or unintentionally, by an intermediate carrier. The introduction of an additional communications path over which notification messages are forwarded from signaling monitoring equipment in the origination network to signaling monitoring equipment in the destination network allows for a significant reduction in the memory storage requirements at the destination network and in the amount of processing required to match, compare, and evaluate signaling messages.

Abstract: Embodiments of the present invention relate to methods and systems for making a call. Such methods and systems may request the call using a network, initiate a first leg to a caller device based on the request, initiate a second leg to a receiver device based on the request, connect the first leg and the second leg to make the call, and bill the call to a account associated with the subscriber.

Abstract: A communication network includes an SS7 Security Gatekeeper that authenticates and validates network control messages within, transiting, entering and leaving an overlying control fabric such as an SS7 network. The SS7 Security Gatekeeper incorporates several levels of checks to ensure that messages are properly authenticated, valid, and consistent with call progress and system status. In addition to message format, message content is checked to ensure that the originating node has the proper authority to send the message and to invoke the related functions. Predefined sets of templates may be used to check the messages, each set of templates being associated with respective originating point codes and/or calling party addresses. The templates may also be associated with various system states such that messages corresponding to a particular template cause a state transition along a particular edge to a next state node at which another set of templates are defined. Thus, system and call state is maintained.

Abstract: Methods and systems are disclosed for making a call. In one embodiment, methods and systems may request the call using a network, initiate a first leg to a caller device based on the request, initiate a second leg to a receiver device based on the request, connect the first leg and the second leg to make the call, and bill the call to a account associated with a subscriber.

Abstract: The method for providing an efficient and adaptive management of message routing in a multi-platform, communication system having dynamically changing platform populations and dynamically changing connectivities between platforms where each of the platforms are capable of performing the steps of recognizing at least certain ones of the platforms in the system, deriving from at least one of the recognized platforms the quality of interconnectivities of the recognized platforms and certain others of the platforms in the system; and employing the derived quality of interconnectivities to make connectivity-based routing decisions using a selective one of a point-to-point routing algorithm, a point-to-multipoint routing algorithm and a broadcast routing algorithm.
