CAR is to drop packets on an incoming interface if they exceed a certain threshold. It's also known as policing in FR terms. It really has nothing to do with QoS (it does, but it's not the correct application for this situation).
Your best bet is to take his PBX traffic, and reprioritize it from 6 to 46 (EF) and give it a certain bandwidth over the WAN. Furthermore, I'd recommend not doing the 0 CIR with bursting, as all the packets leaving the router will be marked DE. I have come across a few customers the past few weeks saying that the carrier PROMISES they won't drop any traffic due the 0 CIR, but just know that they can because the customer has no CIR, and dropped voice packets = unhappy users.
