Ok have looked a bit closer, it works for ordinary calls, my problem is actually 
with queuing. The call isnt going to the phone (at least the inuse counter stays 
at 1) so it must either be asterisk adding the ring sound to the stream (doesnt 
seem likely) or the queue app is ignoring incominglimit

i've just started to look at the code to see if i can spot whats going on but 
this is my first time in doing so for asterisk so i'm not familiar at all with 
its inner working! :)
