 Subject:  Traffic Shaper + VoIP
 Date:  Mon, 22 Nov 2004 15:56:25 -0500
I was wondering....I have 512/512 DSL and when my connection is taxed 
either up or down, even with just normal surfing which might max the 
connection for a few seconds, my VoIP quality suffers a bit.  I used the 
shaper wizard to create a basic shaping setup.  I've then added a static 
IP assignment for my VoIP adapter and created and up and down rule that 
sends any traffic leaving from or destined to that IP in to the highest 
priority queue.  I am just wondering if it's possible that the shaper 
can not react fast enough to keep the VoIP calls 100% clear.

I was thinking perhaps I should create a separate pipe of 100 kb just 
for VoIP that would always be in reserve.  I realize that my main 
connection would be robbed of that bandwidth, even when it is not in use 
(a limitation of the m0n0 shaper right now).  But, I do not upload or 
download enough that I'd miss that speed very often.

Is that a wise move or should I be looking to do some other setup 
perhaps?  My VoIP adapter has QoS capabilities, but I'd really rather 
keep it on the inside of my m0n0 and not between m0n0 and the DSL 
modem.  I've seen people suggest putting the adapter after m0n0 and 
before the rest of the LAN, but I'm not sure how to exactly set that up 
so that the adapter gets and IP but does not pass it long as a bridged 

Anyway, before I ramble too much, if anyone has ideas on how to best set 
up m0n0 and VoIP, I'd love to hear it.
