[c-nsp] QoS not working - VPN acl conflicting???

Still stuck. Keep in mind that I am trying to make the QoS policy work on traffic that is NOT going over the tunnel. This is voip traffic going to my provider. I tried using the qos-preclassify command at the crypto map level and the tunnel interface and then did huge transfers from branch to branch just to saturate my T-1 and it did, but the policy never reserved/prioritized my voip traffic.
 
Serial0/1/0 is up, line protocol is up
  Hardware is GT96K with integrated T1 CSU/DSU
  Internet address is x.x.x.x/30
  MTU 1500 bytes, BW 1544 Kbit/sec, DLY 20000 usec,
  reliability 255/255, txload 231/255, rxload 16/255

  Service-policy output: VOIPpm
    queue stats for all priority classes:
      queue limit 64 packets
      (queue depth/total drops/no-buffer drops) 0/0/0
      (pkts output/bytes output) 0/0

    Class-map: VOIPcm (match-all)
      0 packets, 0 bytes
      5 minute offered rate 0 bps, drop rate 0 bps
      Match: access-group 156
      Priority: 33% (509 kbps), burst bytes 12700, b/w exceed drops: 0

    Class-map: class-default (match-any)
      1437759 packets, 848687414 bytes
 
>From my research,  it looks like the qos-preclassify command only affects traffic going over the tunnel. Any help would be very much appreciated.
