  I will do my best to research before I post.

  My comment was about a channel going into and out of several contexts
  during a call.  I understand that the execution of the dialplan is linear,
  and that a context is merely a "function" of sorts, which jumps to that
  part of the dialplan, executes, then returns to the next action after the
  call to the different context (if that different context allows it).

  I do (now) understand that variables are attached to the channel, not
  contexts.

  Thanks!
