I agree with Ronnie - sounds like the router isn't seeing any interesting traffic. "show dialer" can provide useful information. Depending on what IOS version you're running, it may show the "time until disconnect". If you have more or less constant interesting traffic, it should stay near 120 seconds.
If I remember correctly, "debug dialer packets" will show interesting packets. Use with caution (as with any debug) if you have a fair amount of traffic. Also, remember that interesting traffic has to be defined in both directions - either end can drop the link if there is no interesting traffic out of the interface for the idle-timeout.
