I don't think Kelly's response is correct, at least for TDM FXO boards.
I could not find a way of preventing the FXO board grabbing the line
when it rang, and subsequent enquiries on this list at the time
suggested that it wasn't actually possible - which is a pity, as it
means it is impossible to piggy back Asterisk on a POTS line with other
auto-answering equipment (e.g. data collection terminals).
