Assuming that you have not disabled the inactivity timer then if the ISDN is still staying connected then there is still some "interesting" traffic. You need to identify the interesting traffic and do something about it.
If you have problems figuring out what the interesting traffic is then running debug dialer may be helpful.
As the previous posteer points out it might be helpful if you post the configs.
I would think that it is unusual for a tracert to send out broadcast packets (which seems to be what your show dialer is indicating). Perhaps if you post the output of the tracert and post the output of show ip route from the router we might be able to figure what is going on.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
