Cisco IP Phone 7925G message "DHCP Timeout"

I have the following configured for Cisco IP 7925G Phones

- Call Manager CUCM 6.1.3

- Cisco Wireless Controller  5508  ----  WLAN configured for  WPA2 with 802.1X + CCKM

- Cisco ACS 5.3 for  Authentication  WPA2 with PEAP

- Cisco Wireless IP Phone  7925G  WLAN configured correctly

- DHCP is Windows Server 2008 R2 with Option 150 on the DHCP Scope plus Gateway, DNS , etc

The Cisco IP Phone 7925G is able to connect to the WLAN correctly . i can see from ACS that the authentication is successful but it can not get the DHCP IP assigment , it is stuck with Configuring IP and then DHCP Timeout . I have tested it , i can connect manually to through the WLAN and get a DHCP IP assigment. I have also run a " Debug DHCP Message " on the WLC 5508  but i don't see the DHCP communication from the IP Phones's 7925G MAC address.

am i missing something ? any help before i sink. SOS !!!!!

Did you ever figure this one out?  I am having the exact same issue.

Have you edited the DHCP proxy and relay variables on the WLC?

Had similar issues to this at a customer before and it was rectified by removing the DHCP proxy setting.

Also ensure you have DHCP relay enabled for the vlan that the 7925G is connecting on.
