We had this request at least once more on the forum. The feature you require is not implemented in the software so you will need to make some tweak to achieve your goal.
This is how it could be done:
For a start you will need some scheduler to run a batch-file that pings at regular times to activate the line. The extended acces-list matching the dialer should only include these two adresses: scheduler host, dest host.
This will cause the dialer to stay up for a period of time equal to the idle time.
As no other traffic matches the dialer-list, the idle time will never be reset, except by renewed activity from the scheduler host. Linux crontab could do this perfectly, with windows it will also be possible through a variety of utilities.
However, this is a method for which I want to state: Do not try this at home!
Please be aware of the unfriendly characteristics that are involved in using DDR in this way. It will work, but that is just it! There might be better alternatives depending on your specific situation.
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
