Policy-map voip Class voip Priority 256 Class class-default Fair-queue Interface fastethernet 0 Service-policy output voip Above is what I do to prioritize 256kbit of outbound bandwidth to voip calls, adjust accordingly. You must also use the qos pre-classify in your ipsec tunnel definitions for this to work, but it does work well. I know I'm potentially mapping other traffic than voip, but I'm lazy and don't want to classify the rtp and sip and iax ports, rarely does the box do any other traffic than voip as updates occur in off hours. You'll probably additionally want to match your ipsec keying traffic and give it priority bandwidth, if you're going to push voip through the tunnel you'll find yourself rekeying more often and want to make sure on a saturated link it gets priority so the tunnels don't drop. If you're on DSL, you probably want to research cascading the Qos, have a root policy that throttles all bandwidth to a certain speed, then a child policy that prioritizes that bandwidth, so you don't saturate your outbound circuit(think in terms of P2P protections).
