Sorry Ermal. I've been too busy to try this again and I won't have a chance again until next week. I will try to get screenshots though.
Okay, I tried again today with total bandwidth being 1.3Mb/sec and choosing 320Kb/sec for VoIP. I get around this by choosing 25% instead of 320Kb/sec. This is on a T1 with 1.5Mb/sec actual bandwidth.
