Having a zero reply out there looked like we were not capable, so this is a null void response to change the numbering landscape of the post is simply a consideration of incremental numerical indexing that changes a void integer to a single digit integer.

bf6b5yr, that explained it pretty good. That was the thing I hadn't seen yet in this post, the fact that it isn't one frequency, but a combination of frequencies. That's why it's called "dual tone". At least I hadn't seen it before, the diagram shows it, if you understand the diagram.
