We have the same issue, and I think I've figured out what's causing it,
by watching the SIP debug output.  

What I noticed is that when someone misses a call on the queue, it
switches over to the next person, but almost immediately (after a short
ring) it breaks off and cancels that call because of a timeout.  I
think it's a matter of timing between the different timeouts you can
set in queues.conf.  I haven't had time to tweak it yet, so that's all
I can tell you.  I don't know how hard it would be to get the timeouts
to jive perfectly, but I'm sure it can be done.

Mind you, this is based on only one observation, so I may be
wrong...  It's only a minor annoyance, and I have bigger fish to fry
right now.  Speaking of which, one of them is almost burnt, so I have
to go. ;-)

I'd be interested to hear your findings...
