I'm not sure that this is what exactly You need, but I have a patch
for app_queue
that will store and update queue callers (as well as update lots of
fields for queue members) in realtime mysql table. This allows to do
many requests for current queue state simultenously, and moves load
from asterisk to mysql (which can be on separate machine). So,
generally to get active callers with all their callerid/channel info
You will have to do just "SELECT * FROM queue_callers".

It's not very finalized, so I haven't yet posted that to Digium for
inclusion in next asterisk versions, but I intend to do that in
future. It's been working stable on our production for several months.

If You're interested, please reply, and I'll try to separate that
patch out from other our patches.
Currently I have it updated for 1.4.19, but also have some version for 1.4.14

Atis
