RE: CDP enable after factory reset cause the phone can't obtain IP address

Are you connecting phones to Cisco switches? If so, do you have CDP configured on your switches?

If setting CDP to disabled on the phone solves the problem, that is usually an indicator that you are using Cisco switches with default Voice VLAN/CDP advertising setup. If you do not want this/aren't using it, you should be turning it off on your switch, not relying on the phones to ignore it...
