1. An optimizing communication system comprising:

  • a plurality of nodes including a source node and a desired destination node, said source node comprising means for packetizing voice information, and said desired destination node comprising means for restoring said packetized voice information, wherein said packetized voice information uses at least some bandwidth,wherein said means for packetizing voice information embeds a sequence number within each packet;

    a single switching means operably connected to each of said plurality of nodes for receiving packets from said source node and switching said packets to said desired destination node;

    means for dynamically adjusting said at least some bandwidth used by said packetized voice information during periods of high packet discards by increasing compression of said packetized voice information when a gap in the sequence number is detected at the destination node; and

    means for dynamically adjusting said at least some bandwidth used by said packetized voice information during periods of low traffic by decreasing compression of said packetized voice information.
