Hello,

as with any tunnel use "qos pre-classify" on the tunnel interface config. The router will remember the original IP header before encapsulation and you can then match on RTP and such. The mapping of IP precedence should be done appropriately according to the standards. So basically the output policy would look evry similar to normal IP traffic.

Hope this helps.
