1. A method of embedding in band call flow logic history within a call request for passage through a distributed call system, said method comprising:

  • embedding a first group of characters representing specific events in a logic flow of said call request, relevant to a first component device in said distributed call system;

    embedding a second group of characters representing specific events in said logic flow of said call request, relevant to a second component device in said distributed call system; and

    communicating said first group of characters and said second group of characters are communicated in-band within said call request as said call request traverses said distributed call system; and

    wherein said specific events are unique with respect to any given component encountered during said call flow.
