VoIP on MetroE 5U / 5D - Asterisk and pfSense 1.2.3

[pinoyboy]

We have around 5 Up MB and 5 Down MB MetroE speed with our provider and I enabled traffic shaping.  I downloaded a 200MB CAD file and saw how traffic saturated the link, and VoIP traffic were being dropped.  See the settings and please help with any suggestion.

We just installed Asterisk, and can not move to pfSense 2.x until end of year.

Thank you!
