Traffic Shaping

Can someone please school me on how to configure the Traffic shaper or Monowall in general, with regards to using VOIP phones.  My service provider asks that I have ports 5060 and 10000-30000 open.  If someone has already addressed this issue, please link me to that thread.

Just a few details:  I am using NAT.  We have a block of static addresses.  When I configured the router, we could receive calls, the caller could hear our voice but we could not hear theirs.  So, it "almost" works. 

I guess you are using Magicjack also.
Open port UDP 5070, TCP 80, TCP 443 as well. I open UDP 10000-65535 per an article I saw on the internet.
I used mgraves screencast:

Reserve traffic for all UDP ports necessary in your rules. 120K is enough for one call at a time. 256K covers 3 calls. Check the speed charts as you talk on the phone.
I put Magicjack on a DMZ with a dedicated computer.

I'm not using MagicJack.  We are using Nextiva for about a dozen or more office phones.  They use the SIP protocol.  I know there is some kind of work around, but can't seem to locate any instruction on the configuration.  The best I have been able to locate are some notes on using sip.conf, but no other documentation.  Any help would be appreciated.

what worked for me, NAT these ports to my PBX box, connecting to Flowroute service:

UDP 5060 (SIP Signaling)
UDP 49152 - 53246 (RTP Traffic)

back to an actual "Traffic Shaping" question...  I looked in the FAQs and didn't really see anything useful in the documentation or FAQs

I setup two entries (upload & a download) in my Traffic Shaper... and I have NO idea if I even did it correctly (source/destination, upload/download priority, CoS/TCP settings, etc etc)

how and what settings/options give the highest priority for one specific machine
