we'er just starting to do some video conferencing across the wan as well as our first 2 sites doing voip. we are having a disagreement. one guy says video is more sensitive to latency than voice. he asserts we should mark video as a '5' and then voice as a 4. I'm hearing that even if that is so, users will have much less tolerance with voice than with video. so i'm saying mark voice as 5 and video as 4.
