You could further refine these login and logout routines to take into account that the
AQMSTATUS and RQMSTATUS channel variables are set each time AddQueueMember() and
RemoveQueueMember() are used. For example, you could set a flag that lets the queue
member know they have not been added to a queue, or even add recordings or text-
to-speech systems to play back the particular queue that is producing the problem.
Or, if you’re monitoring this via the Asterisk Manager Interface, you could have a
screen pop, or use JabberSend() to inform the queue member via instant messaging,
or…(ain’t Asterisk fun?).

Chapter 12: Automatic Call Distribution Queues
Advanced Queues
In this section we’ll take a look at some of the finer-grained queue controls, such as
options for controlling announcements and when callers should be placed into (or
removed from) the queue. We’ll also look at penalties and priorities, exploring how
we can control the agents in our queue by giving preference to a pool of agents, and
then increasing that pool dynamically based on the wait times in the queue. Finally,
we’ll look at using local channels as queue members, which gives us the ability to per‐
form dialplan tricks prior to connecting the caller to an agent.
Priority Queue (Queue Weighting)
Sometimes you need to add people to a queue at a higher priority than that given to
other callers. Perhaps the caller has already spent time waiting in a queue, and an
agent has taken some information but realized the caller needed to be transferred to
another queue. In this case, to minimize the caller’s overall wait time, it might be
desirable to transfer the call to a priority queue that has a higher weight (and thus a
higher preference), so it will be answered quickly.
