For me, this hasn't seemed to fail me. However, I may just have been lucky
not to have had many instances of uploads/downloads hogging at the same time
as a VOIP session (Viatalk and Vonage prior to Viatalk).
I use the Magic Shaper Wizard for the Traffic Shaper, trim out all the
download rules and pipes since I don't do inbound shaping, and add this rule
right above the m_Catch-All Upload Bulk rule. Seems to work for me.
If Proto Source Dest Target
WAN <- * OPT1 * m_High Priority #3 Upload <- My VOIP
