I felt the same way after I looked at doc CD..
Usage Guidelines
When the cumulative load of all UP links (a number n) exceeds the load threshold the dialer adds an extra link and when the cumulative load of all UP links minus one (n - 1) is at or below load threshold then the dialer can bring down that one link. The dialer will make additional calls or drop links as necessary but will never interrupt an existing call to another destination

Dan,
I believe you're mistaken. Dialer load-threshold will also drop a channel
if the load remains below the load-threshold long enough. Remember, the
period during which the load is evaluated is determined by the dialer
interval-period which, by default, uses 300 seconds (5 minutes).
Does anybody disagree?
But, on the other hand, it doesn't take 5 minutes for utilization to exceed
the load-threshold for the 2nd channel to be added. Go figure.
