1. A method for transmitting aural signals across a wide area digital data network and a target phone system, comprising the steps of:

  • receiving a first aural signal having a first configuration, said first aural signal representing a voice signal;

    converting said first aural signal into a first data signal having a first network configuration that can be transmitted through a first local area network including the steps of;

    converting said first aural signal to a digital signal;

    generating first and second data transmission unit signals, having said first network configuration, from said digital signal, said first data transmission unit signal includes;

    a first voice unit signal; and

    a correction unit signal including a representation of a second voice unit signal from a second data transmission unit signal, transmitted separately from a first data transmission unit signal, said correction unit signal for recreating said second data transmission unit signal if not received by said destination converter;

    wherein said first data signal represents said first data transmission unit signal;

    transmitting said first data signal to a first communication device through said first local area network;

    transmitting said first data signal from said first communication device to a second communication device in a second local area network through the wide area digital data network;

    transmitting said first data signal to a destination converter through said second local area network;

    converting said first data signal to a second data signal that is compatible with the target phone system; and

    transmitting said second data signal from said destination converter to a first receiver via the target phone system;

    wherein said steps of receiving a first aural signal and converting said first aural signal are performed by a PC-phone.
