So since no one has responded, this either means one of two things:
Either I am an idiot and missed something obvious and therefore no one 
wants to deal with me. Or this is indeed not something typical of an 
asterisk config.

Can someone at least point me to which? :)
As I mentioned, everything is working, it just doesn't "feel" right.
