Sounds like you need to use floating statics along w/ interesting traffic to
get what you want.
You can have a static route for the network that you want to monitor, with a
high distance. Then if your routing protocol fails for any reason your
floating static will point to the other side of your ISDN call. Interesting
traffic will determine what type of traffic will bring up and keep up the
call.
Make sure that you build your interesting traffic properly. Deny your
routing protocol as interesting or the call will never come down. I usually
also block NTP, SNMP, ICMP, and other commonly used management traffic
types.
I use this same setup for about 300+ ISDN sites that work 8x5x5 or 8x8x7.

Exactly my point! Any Cisco listeners out here .
Dialer watch is a solid backup for a 24/7 client
but for 8x5x5 clients it is not.
When the client gets the $500 bill for being up
18 hours on a Sunday due to a DAX eating itself,
it is not, "Great Job" that I typically hear in response.
How about an option where the idle time out, after
a dialer-watch event, sets a flag converting to DDR
then clears the flag when the route comes back?

even define a dialer-group.
