I hear a newer IOS supports OSPF....

As I recall dialer watches work only with IGRP and EIGRP. If you need OSPF
then the demand circuit is the best way to go.

A demand circuit is useful if you really msut run OSPF over an ISDN line.
A better answer to this problem is to use a dialer watch-list, a very cool
facility used to trigger DDR when a 'watched' route is absent in the routing
table.
This is great for a number of reasons.
1) Packet switched networks are not the best at telling a DTE when there's a
problem in the cloud. Examples being ATM and FR
Interface may stay up/up even if the remote is down.
2) You can place a DDR in a place further into your network rather than on
the same router as a critical link and still have DDR work when the link
fails if the routes being watches originate beyound the point of failure.
Regards,
Jeremy.

Another thing to keep in mind is that ospf demand circuit will cause the
isdn circuit to come up when there is a topology change.. So don't be
shocked when it comes up every once and awhile.

That's no trick, use ospf demand circuit
