With the standard options your are right, you can limit the incoming 
calls that *enter* the queue. But AFAIK, there's no way to limit how 
many calls *leave* the queue. You only have a timeout to control *when* 
a call leaves the queue, not *how many* of them. With that been said, I 
only can think of a dialplan solution, that could fit your needs or not:

1. Queue your call normally, with the standard timeout you want
2. If the call leaves the Queue, it will continue dialplan execution at 
next priority, and there you can make it be part of a group of channels.
3. Count that group and check if it reached the *limit* you need. If 
above the limit, *requeue* your call to the same queue it was.

That's all I can think of, without a hard work of messing with 
app_queue.c source code. Hope you get the idea.

Cheers,
