    Gday All,

    We have a cisco call manager sitting on a 2851, a cisco 1841 with a dsl connection of which a vpn tunnel connect to a cisco 881. Currently we have the phones at both sites working, but I now need to apply QOS across the vpn tunnel so that the ip phones get priority over all else.

    I assume I define the policy, and apply it to both ends of the tunnel on the virtual template?

    Sounds like a pretty good start :)

    Some of the easy rules of QoS

    Classify and mark on ingress into the network.

    Queue on egress, shape/police where required.

    I assume you are already shaping the tunnel to operate at the slowest line rate minus overhead? Just add it to that.


    Other option is GETVPN and just normal qos...

    On top of all that good advice, it's probably worth ensuring that you're using "qos pre-classify" on your tunnel interfaces
