QoS settings for Tomato router

Can anyone recommend QoS settings for their Tomato router that are confirmed working with Voipo? I'm working through a support issue and questioning my setup.

I have 40KB/s upload via Earthlink. Here is my configuration allocating up to 80% for VoIP.

I then classify via the IP of the PAP2T rather than ports (ignore Viatalk; now Voipo):

I've verified that this appears to classify call traffic data via their realtime GUI, but wondered if someone had some suggestions on how I can tweak the configuration to allow Voipo as much outbound as possible and make it so it trumps all other traffic.

Thanks,
Brian

Have you tried the service without any QOS?

Do the results tell you that you need to fuss with it?

I don't use Tomato. If the router looks at IP precedence or DSCP bits of the packets then you don't have to reclassify the packets and allocate bandwidth. I would start with enabling QOS and do lots of downloads/uploads ( you can upload photos to google photos, download apps) and see if the voice quality changes. If voice quality is good then don't do anything else.

If it does, then you can reclassify the packets based of source MAC address (or IP address if router does not provide that) and allocate 170 bps (for three way calling, about 85 for each call) for the Voipo adapter.
