I agree with you. My problem was the link was flapping even when the watched
route was in the routing table, which means the primary link was UP. So, the
primary link was UP and dialer-watch kept the BRI interface flapping even
though there was no traffic thru the link, nor hello packets ... When I
removed the dialer-watch group the BRI interfaces became stable.
Not sure, but I assume that was something wrong with dialer-watch itself.
Since I was given access to that ISDN lab for one day, I couldn't test
dialer-watch anymore, had to skip it ...

I have never had it working properly either, but I think that our definition
of working properly may be different from Cisco's where dialer watch is
concerned. According to a document I found on CCO, notice the part in caps:
After the backup link is up, the primary link is checked again at the
expiration of each idle timeout. IF THE PRIMARY LINK REMAINS DOWN, THE IDLE
TIMER IS RESET. Since the router should periodically check whether the
primary link has been reestablished, configure a small value for the dialer
idle-timeout. When the primary link is reestablished, the routing protocol
will update the routing table and all traffic should once again pass on the
primary link. Since traffic will no longer pass across the backup link, the
idle timeout will expire and router will deactivate the backup link.
Now to me, that means that as long as the route via the primary is down, the
line stays up, and that is what I have seen with dialer watch. So I don't
see what the point of a dialer-list is, if the line is going to stay up as
long as the route is down anyway. I spent about 6 hours one day trying to
fix it when it was never broken. Of course I could still be way off base
here, but I took configs exactly as they had them on CCO and this is the
behaviour I saw. According to the document, at least what I get from it, it
is the proper behaviour.

To be honest, I've never seen dialer-watch working properly .... I also
tried 12.0.x and the link never stopped flapping ... I made sure I was
doing everything all right, no hellos thru the link, no broadcast, no
nothing; even the route was still in the routing table and the link kept
flapping due to dialer-watch ....
I just know it works like that theorically, never got to try it with
12.1 or higher.
I would not get mad if someone clarifies this and tell me I'm worng
since I'll go to the lab and find out whether this is true :-)
cheers,
hockito

I have tried this but no luck can u tell me which IOS on u have tested
this.
I tried this with 12.0(9)
although Cisco say that dialerwatch was unstable till 12.1(7)T.

issue a
timer for dialer-watch to wait before start "watching" a route to make
sure
that route it's in the local routing table:
