[asterisk-users] How to know Caller's last position in Queue?

[Asterisk Man]

Hi group,
I have a simple call center scenario set up on Asterisk. Customer calls the
DID and gets placed in Queue waiting for their turn to talk to the available
agent.
Sometimes Customer hangs up in between and in this case I want to get the
last position of customer in Queue.
I know there is a variable called ${QEORIGINALPOS} that gives us original
position of caller in Queue, but there doesn't seem to have something
similar for exit position.
Am I missing something?

Thanks,

--AsteriskMan
