Hi there,

I don't seems to find any information about skype qos - I would assume I could do a qos only on the skype port - but I read somewhere else that I should work with l7-protocols. I am not sure which road to take from there... any kick in the right direction would help.

It seems that there is no luci apps for the qos

d I am on buffalo nfinite wzr-hp-g300nh with backfire 10.03

i've just set a qos for skype-to-skype call using luci-app-qos and l7filter. It's not a really qos, it's a packed shaping, but works fine for me.... I don't think that is possible to make a real qos for skype voip call.

A practival advise is to put small udp packets in a high priority class.
Ex.)

${IPTABLES} -t mangle -A PREROUTING -i ${WAN} -p udp -m length --length 0:412 -j MARK --set-mark ${CLASS_HIGH}
${IPTABLES} -t mangle -A POSTROUTING -o ${WAN} -p udp -m length --length 0:412 -j MARK --set-mark {CLASS_HIGH}

Variables are self-explanatory.

Yes, but are VoIP packets small?

Also, I'd suggest using something that does not have so many surprises included, like say FOSS Skype Alternative: Mumble.

Definitely, yes. In addition this solution is simple and boosts another delay-critical services that also need high priority.
