Setting up QOS on 831 for VoIP

I have a Cisco 831 Router running code version 12.3. I am trying to setup QOS for VoIP (using SunRocket). I have set a couple things up, but while I'm talking if I do an upload test quality is terrible. Downstream is fine even during a test.

I have Charter as my ISP, and I consistently get 2.9 Mb down/240 Kb up using Speakeasy's test.

Here is my current config:

It seems to me that you only have the QOS policy applied one way. Output on your LAN port would indicate that you are shaping on Downloads. If you want to shape on uploads, apply a QOS policy output on E1 as well. However, you may wish to create a new policy due to the fact that your connection is not symetrical.

Hope that helps,

Jim
