dsl modems with QoS (aka TOS)
Are there any consumer DSL modems that offer QoS (eg. separate tx queues)?
My outgoing DSL traffic will sometimes have short bursts that saturate the link for a second or two. That of course kills quite a few voice packets and makes the VOIP sound quite bad for the other guy.
After playing with tcpdump and tweaking everything I now have all my VOIP data (sip/udp and rtp/udp) marked with the elevated IP precedence of 0xb8. Now all I have to do is find a DSL modem that has at least two internal QoS queues. Are there any such things? A quick google didn't turn up anything in consumer price range.
I'm trying to avoid buying a Sangoma PCI DSL card and doing it all in software.
