1. A method for implementing an interactive decision tree protocol, comprising the steps of:

  • accepting a first request from a user to establish a first bidirectional communications link;

    connecting said user to an interactive decision tree-based expert unit supporting a decision tree;

    transmitting to said user a series of option sets via said bidirectional communications link, each option within one of said option sets determining a subsequent set of options, each option set defining a node on said decision tree, and an assembly of all interrelated option sets defining said decision tree;

    receiving a request from said user to exit said decision tree;

    assigning a decision tree node identifier to said user, said decision tree node identifier being indicative of a last node visited by said user in said decision tree prior to said exit request;

    accepting a subsequent request from said user to re-enter said decision tree via said expert unit; and

    reconnecting said user to said last node in said decision tree based solely upon said decision tree node identifier associated with said user identification.
