"Couldn't contact DHCP" error
I got "Couldn't contact DHCP" error on my one Polycom SoundPoint IP 320. And, when I disabled the DHCP feature and set static IP address, the phone worked normally.
While the other phone, can contact the DHCP server and get IP address.

Check on the router if you are distributing enough IP addresses.
