Well, the trouble that you are seeing is prolly caused when say for example you bring a SErial interface down on one end, but the switch(carrier network) reports the link as being up to the serial interface on the other end, so it doesnt switch to ISDN. I have seen this issue with particulary ATM circuits, wherein both the ends are isolated by switch(Carrier network) and the status is independent of either ends.
The key is to use dialer watch and a dynamic routing protocol (pref. eigrp), which basically tracks the status of a route in the routing table, absence of which triggers a back up interface. So it doesnt rely on interface status.
