1. A dual switching matrix fabric, comprising:

  • a packet switch fabric configured to receive packet traffic from a plurality of packet transmission links, wherein the packet traffic includes multiplexed voice streams; and

    a TDM switch fabric configured to receive TDM traffic from a plurality of TDM transmission links;

    wherein the packet switch fabric and the TDM switch fabric collectively perform per-voice-channel switching between the packet and TDM transmission links and between different packet transmission links, wherein performing per-voice-channel switching between the different packet transmission links includes de-multiplexing the voice streams into individual voice channels, switching the individual voice channels individually according to a path of each voice conversation, and re-multiplexing individual voice channels sharing the same next hop onto the same outbound packet transmission link.
