To what extent, practically, in today's world, does QoS impact voice
My understanding is that such is not very well executed beyond my
demarc, so I can prioritize my own traffic out to the ISP, but all
bets are off after that. And, ISPs have so much more bandwidth than
the house, and I'm guessing that combined with you don't receive what
you don't ask for (if you're sending out more voice and less torrent,
you will likely receive back more voice than torrent), practically
speaking there is at least some impact.
So, my guess is there is some impact to in-house QoS, perhaps not 100%
adherence end-to-end, but some. Am I guessing reasonably?
