dynamic tagged and untagged vlan assignment

[Stieven.Struyf at komatsu.eu]

All,
Currently i use this configuration to assign clients an ip after 
successfull authentication (mac authentication):
user User-Password == "password"
 Tunnel-Type = VLAN,
 Tunnel-Medium-Type = IEEE-802,
 Tunnel-Private-Group-id = "20"

This works, but now we are deploying a cisco iptel solution.
The phones need to be in a tagged vlan instead of an untagged. 
Can i make this distinction based on radius attributes?

regards,
