VoIP Clients. ATAs. This is an inside-to-outside problem.

My bandwidth is very very limited. Not more than 140 Kbps on both
sides at any time. I use G729 as a codec in order to reduce
consumption. Use the pf.conf below, when VoIP is the only traffic,
the quality of the calls is excelent with no voice cutting at all.
Now if I start a download I immediatelly see the quality degrade.
That is why I thought of using some radical policy.
I would appreciate any comments on this ruleset.
