The problem is that several parallel instances of the Dial application are 
happening at the same time on the local channels. None of these parallel 
instances know of any of the others, so they continue to ring even though one of 
the Dials has been answered.

Right now there's nothing that can be easily done about this from your end, 
unless you have the ability to not use local channels for your queue members.

In writing this response, I wonder how easy it would be to make that answer in 
your gosub get pushed up to the queue application so that it can hang up the 
other local channels it has dialed. I think I'll set this scenario up and see 
what I can find out.
