7920 Wireless Phone - WLSM - And Voice QoS

I'm trying to apply Cisco best practices to Wireless Voice.

However, because I'm using a WLSM a lot of the best practices are difficult to implement.

For example, how can you police/rate limit the FastEthernet Port on a switch if the AP terminates one side of the GRE Tunnel. The traffic isn't clear so how will the switch be able to do rate limiting? (1Mbit for voice traffic and 6Mbit for data traffic).

Also, what about changing the COS to DSCP values?? The 7920's mark voice traffic to a COS of 6. Cisco best practices tells you to remark it to 5 so that it matches up with a DSCP of 46 (to match the rest of the AVVID network settings). Again, if it isn't in the clear how can you do this??

Finally, all my AP's are on switched ports, not routed ports. In addition, I can't put a L3 service policy statement (used to mark traffic via the IP Address of the tunnel itself!) on a switched port! (I'm using one GRE L3 tunnel specifically for voice).

Any ideas? If there was no GRE tunnel it would be fairly straight forward!

Thanks,

Paul
