DHCP proxy is currently disabled but I have tried it enabled as well.
I have two 7925 wireless phones. One is set up for DHCP, one is set up with a static IP and DNS, DHCP Server and TFTP server.
The CME router is set for auto-reg-ephone and I have manually added the phone that I manually configured which seemed to make sense. But neither phone will join the CME. Wired phones are found no problem.
I have noticed that I can't ping the DHCP SVI IP address from the WLC.
WLC Management ip is 192.168.0.5/24 and is VLAN 1
Phone VLAN is 192.168.50.0/24, SVI is 192.168.50.2, CME sub-if is 192.168.50.1. The 2960S is the DHCP server.
I can ping anything on VLAN 1 from the WLC but nothing else.
Appropriate DHCP scopes are set and include Option 150, Import all and DNS server IP's as appropriate.
