Marco,

The DHCP server in the WLC is not fully functional. You can only set the subnet, GW and DNS that the client uses. You can't set any of the advanced features, like option 150 for the TFTP server.

Now, under the interface for the phone subnet, what do you have set for the DHCP server? if you set it to a router/switch/server the WLC will proxy the request to the device. and the client will get the correct address.

If you are using a secrity device, this won't work. You'll need to disable DHCP proxy.

From the GUI Controller > Advanced > DHCP, and uncheck the box.

From the CLI config dhcp proxy disable

Once this is done, make sure you have the ip helper-address under the L3 interface and point to the DHCP server.

HTH,

Steve
