I'm not quite clear on what your criteria are, but it sounds like floating static routes might suit you (and change the idle-timeout value for the ISDN to ten minutes). Floating static routes are routes with a high administrative distance, that are normally overridden by another route (usually dynamic, I assume static is also fine) pointing to your leased line. If the leased line goes down, that route becomes inactive, and the floating static route (pointing to the ISDN) takes over. You will need to define interesting traffic.
