[Asterisk-Dev] Anyone doing QOS routing on Linux for SIP/RTP?

What I *really* want is QoS on my access line to my ISP.  I have a 144K
SDSL (only thing available at my location) and I receive some fairly
large e-mails at times.  I don't want congestion on my link between me
and my ISP to cause problems with my VoIP calls.
