We're trying to PQ (Priority Queue) packets on a Cisco using ACL's.
-------------------------------
 
You do not want to use PQ for voice QOS.    You will still receive far too
much jitter.   Instead configure LLQ which was specifically designed for
voice scheduling on an interface.    Aside from being designed for voice,
LLQ also allows you to create lower priority queues for other traffic
without running into queue starvation problems.
 
For a complete description on designing and configuring Cisco networks for
voice QOS see:
