cisco phones

Peace, I still can't authenticate the ip phones using md5 on the voice vlan, they keep getting authenticated on the data vlan. I ducked ducked the internet and found that: "device-traffic-class=voice:= Cisco-AVPair" Must be added. So I added it username of the ip phone in daloradius but the behavior has not changed. Perhaps, that must be added manually to the users file for it work. I only found documentation on how to do that in cisco ACS.
