No, the channel has to be in Stasis to control it. The ability to move a 
channel into Stasis arbitrarily is on the feature wish-list[1].

Generally instead of doing that people have been replacing the Queue 
application with their own ARI application instead. Since the channel is 
then always in Stasis they can do what they need to connect it to the 
right place. It also makes it easier to implement different strategies 
and business logic.
