1. make a network-extension dial a method for a traditional extension, an enterprise phone network packet, containing this network-extension and this traditional extension, is characterized in that the method comprises the following step:

  • A () receives a Dialog request from this network-extension, this Dialog request comprises the traditional extension number that this traditional extension has;

    B (), in response to one of network-extension number and traditional extension number corresponding relation, distributes one of RTP (real-timetransportprotocol) channel internet address (IPaddress) and Single port (port);

    C () transmits the distributing signal comprising this internet address and this port, make between this network-extension and this traditional extension according to the mutual transmission of voice packets of this distributing signal;

    D this traditional extension number in this Dialog request replaces with a general number of this enterprise phone network by ();

    E (), according to this general number, the Dialog request to transmitted after this replacement has the network gateway of this general number, so that this network gateway transmits ringing signal to voice automaton because of the Dialog request after should replacing through a telephone exchange;

    F () receives a confirmation signal from this network gateway, this confirmation signal represents that this voice automaton replies this ringing signal;

    G () transmits this confirmation signal to this network-extension;

    H () receives a response signal from this network-extension, this response signal is this network-extension because of should confirmation signal and producing;

    AndI () transmits this response signal to this network gateway.
