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.
