Stop Dialing if no Agents waiting

Hello!
we started outbound using vicidial since today.
i have to say it works really really nice!
but i've got a question:
in one campaign about 10 agents are logged in and it works fine with predictive dialing.
in one other campaign everytime only one agents is logged in.
the best solution for this campaign (i think) should be ratio dialing with 3 lines and Available Only Tally set to YES.
it works fine, agent gets free, vici dials on 3 lines.
but if the agents gets a call, the other 2 lines still alive.
it will be nice when vici cancels the open 2 calls...
is it an error in configuration or is it normal that vici waits until the dial timeout gets reached?
thanks for help!!
