Hi guys, I have tried to allocate bandwidth for VOIP sessions using the normal way of HTB qdisc on root class for bandwidth and sfq qdisc on leaf. I also clamp the packet size to 128 bytes to not let large packets interfere with small voice packets. This still gives voice delay when other traffic is present. I read in the mail list that a pfifo qdisc was suggested for the leaf class instead of sfq. I don't have any VOIP kit to test this with so I would please like to know what the final outcome was.
