BCM 450. One analog station will occasionally send another extension (usually the same couple of extensions) a "you have a message" indication. The analog station has no jumper on it. There is nothing connected. I've changed the name of the extension, and the new name shows up at the called extension. I've changed the DN and it still does this. Also rebooted with a power cycle. Still getting the phantom message indication.

I don't see anything in DN's or target lines with the old or new dn. Any thoughts on where this is coming from? Thank you.
