1. An electronic communication network enabling communication between remote locations of a user'"'"'s network telephone facility comprising:

  • a plurality of remotely disposed electronic communications systems coupled to telephone facilities associated with a user'"'"'s network telephone facility, each of said electronic communications systems having;

    means for enabling access to said systems in response to signals transmitted from the user'"'"'s telephone facility;

    message storage means for storing digital representations of audio messages transmitted from the user'"'"'s telephone facility, the user'"'"'s telephone facility coupled to said electronic communication network;

    route storage means for storing digital representations of route data transmitted from the user'"'"'s telephone facility that is coupled to said electronic communication network and associated with the audio messages transmitted from the user'"'"'s telephone facility, the route data indicating an intended recipient of the audio messages;

    means for accessing stored digital representations of audio messages for a selected recipient in response to said route data;

    reproducing means for reproducing each of the audio messages from the stored digital representations accessed by said accessing means to provide reproduced audio messages;

    first converting means for accessing and converting the stored digital representations of said route data associated with said reproduced audio messages generated by said reproducing means to analog tone digit signals such that each of said reproduced audio messages has associated therewith said analog tone digit signals representing associated route data;

    analog transmitting means for transmitting said reproduced audio messages and associated tone digit signals generated by said reproducing means and said first converting means to another of said communications systems;

    analog receiving means for receiving reproduced audio messages and associated tone digit signals transmitted to said communications system from another one of said communications systems;

    second converting means for converting tone digit signals received by said analog receiving means to digital representations of route data, said audio message storage means storing digital representations of said received reproduced audio messages and associated digital representations of route data;

    means for transmitting reproduced audio messages from said reproducing means to a telephone facility of a recipient indicated as the intended recipient by the associated tone digit signals converted by said second converting means; and

    an analog transmission link for interconnecting said analog transmitting and receiving means of said communications systems.
