You're right, the autopause on its standard behavior pauses only the 
member of the queue where it belongs. Taking a little look at 
app_queue.c (http://www.asterisk.org/doxygen/1.4/app__queue_8c.html) you 
can very easily patch the source code to achieve the functionality you 
want. The key functions are:

static int set_member_paused -> Traverses the queues doing all the 
things necessary on all different scenarios (realtime, etc) to pause the 
member you give to it. If there's no queue name given, it with pause the 
member on all queues (the PAUSEALL event).

static void rna -> (as the doxygen doc says) RNA == Ring No Answer. 
Common code that is executed when we try a queue member and they don't 
answer.

If you take a look to the rna function, with autopaused enabled it will 
pause the member if it doesn't answer the queue call after the timeout 
time. You can make it pause all members just by changing this one line:

02164       if (!set_member_paused <http://www.asterisk.org/doxygen/1.4/app__queue_8c.html#d61f43e341bcf4c523f2fdb01ece066b>(qe->parent <http://www.asterisk.org/doxygen/1.4/structqueue__ent.html#59ceee334ec79ed344313a7e8affb3fc>->name <http://www.asterisk.org/doxygen/1.4/structcall__queue.html#188159d17b341b26fcfe4b57baefd372>, interface <http://www.asterisk.org/doxygen/1.4/structcallattempt.html#8ee1350d5c943c7ee1ad3da9078eda25>, 1)) {

to

02164       if (!set_member_paused <http://www.asterisk.org/doxygen/1.4/app__queue_8c.html#d61f43e341bcf4c523f2fdb01ece066b>("", interface <http://www.asterisk.org/doxygen/1.4/structcallattempt.html#8ee1350d5c943c7ee1ad3da9078eda25>, 1)) {


That way we don't send the queue name, pausing it in all the queues it 
is member of.

Although it's not tested, it might work for you. That's the beauty of 
Asterisk and well documented Open Source projects, you can get to the 
code as deep as you want, learn from it how it works, and change 
it/improve it according to your needs. Good contributions make it to the 
official code as well.

Cheers,
