[AusNOG] Voip and QOS

[Alastair Watts]

Ideally your phones or PABX should be setting DSCP for the RTP  
traffic, extra points for setting it for the SIP traffic as well, and  
you should be matching on that rather than a blanket range of UDP  
ports. Otherwise you might end up prioritising traffic using those  
ports that you don't intend to, which may adversely affect the VoIP.

If you're moving to the Cisco 1811 there's plenty of documented  
examples on how to configure this.

Cheers,

Al
