1. An integrated IP network telephone distributor with switching and routing functions, comprising:

  • at least one network interface for receiving and transmitting network packets;

    a memory device for storing a package token lookup table and a package class lookup table;

    a packet classifying device for comparing the network packet received by the at least one network interface with the package token lookup table and the packet class lookup table in the memory device to determine whether the received network packet is a voice package or a data package, the packet classifying device including an unpacketizing circuit, a token comparison circuit, a packet classifying circuit, and a switching and packetizing circuit, the unpacketizing circuit serving for dividing a network packet into a network packet header and a network packet data, the network packet data being stored in the memory device, the network packet header being sent to the token comparison circuit for performing a comparison process, the packet classifying circuit receiving comparison result from the token comparison circuit for being compared with the packet class lookup table stored in the memory device for determining a class of the network packet, the switching and packetizing circuit performing switching and packetizing processes based on the class of the packet, wherein if the packet is a voice packet, the network packet data in the memory device is read and sent to the voice processing circuit, and if the network packet is a data package, the network packet data in the memory device is read and combined with the network packet header to form a network packet for being transferred to a connected computer through the at least one network interface; and

    a voice processing circuit for transforming the voice packet into voice signals for output.
