L3 QoS across wireless backhaul

[timothy.korn]

I recently had to extend my corporate network across the street to a new office we rented.  During testing I noticed choppy VoIP calls  Our only real option was to connect them via a set of wireless bridges so that's what we did. 

I'm trying to setup QoS so that VoIP traffic isn't choppy during their massive file transfers.  We're using Nortel phones so they don't really work the best with Cisco's normal auto-qos setup, and I'm not sure I really need L2 QoS anyways since it's only a single switch and across the L3 link is where I really need it anyways.  If I could just prioritize entire VoIP subnet as it goes out the L3 interface to the wireless bridge, I think that would be good?  I'm not quite sure how to set this up.  Any reccomendations? 

I attached a visio with port configs so you can how the network is setup.  Ask away if you need more info.

Shape both sides to be less than available wireless bandwidth and use QoS to prioritize the VoIP.
