I am looking for a QOS method that allows the best voice quality with little delay and, with the exception of EIGRP updates, I don't care about other traffic. In addition, I would like to use the same QOS config for every 831. I don't want to modify it for each cable/DSL uplink speed. Any suggestions?
The reason is we are having voice quality issues using 831's for a pilot project work from home solution. I knew that voice packets destined for the 831 were delayed when someone at the remote site was downloading a large file but otherwise the quality was pretty good.
More recently, the quality is degrading and it's not just a delay anymore. It appears I have a problem with the QOS method. In the past, the local Cisco office has told me what the Cisco recommended QOS method was. Yesterday I was told that our 831 DMVPN/IP Phone SOHO solution had to do shaping. If I do that, then I will have to modify each config for the uplink bandwidth which I don't want to do.
Currently I am using a config derived from a MQOS PDF found on CCO but I'm not sure it's doing the job. Does anyone have a suggestion on how to make it better?

service-policy output IPTVPNQOS
Output from one of the remote 831's. It looks like the queuing is working since there are no dropped packets but maybe I'm reading it wrong?
