We run a CCP center with MGCP some of our remote sites are having QOS issues (voicemail sounds garbaled to an outside caller, static, jitter, slowness response from the phone). I have configured Auto QOS on every switch port/trunk port, also configure LLQ on the edge MPLS router. When I do a show Policy-map int, I show my priority queue passing voice packets because I can see the packet count incrementing with no drops. Also, on some of our sites the MPLS circuit is usually 90-100 utilized through out parts of the day. I checked with our provider and our "gold" queue is passing traffic without drops as well. Does anyone have any ideas what else I can do to improve the quality of our voice network?
