  • Mechanisms for session border control of VOIP communication from non-symmetric port address translation device
    Patent number: 8755370
    Abstract: In one embodiment, a device comprises an input port for receiving network packets that are being communicated via a computer network. A processor is in communication with the input port. The processor is configured to facilitate dynamic monitoring and updating of port addresses assigned by at least one non-ALG PAT router so as to facilitate communication of packets that are exchanged between an inside user agent and an outside user agent in a manner that mitigates a likelihood of communication interruption during a VOIP session. An output port is in communication with the processor for transmitting packets via the computer network.
