[cisco-voip] QoS

[Cristobal Priego]

correct me if i'm wrong but from what i see on your access list
any udp traffic coming on subnet 10.200.x.x will be marked as ef (46) even
if it's an ftp transfer
i'd modify my access list and create extended access list

ip access-list extended VVLAN-VOICE
  permit udp 10.200.0.0 0.0.255.255 range 16384 32767 any
  permit udp any 10.200.0.0 0.0.255.255 range 16384 32767

so you will make sure that only your voice packets gets to the priority
queue only

just a thought
