I think the deafult codec for ATA is G711, if it is so try to make it G729 (You can have only one FXS port operating with this codec in ATA, this is product limitation). G729 minimizes the bandwidth needed.
Second, as said in the previuos posting use LLQ for voice or IP RTP Priority for simplicity. I recommand IP RTP priority here as you dont want to give any preferential treatment to other data traffic. If you face any difficulty during call setup give preferred treatment to VOIP signalling traffic with CBWFQ (in most of the cases it is not needed).
Since you are using NAT here, I assume you are connecting to local ISP. What ever I said above makes sense only if you have an SLA with your ISP for min end-to-end delay.
