All new web interface with 4.0.1 don't know f the wholes have been fixed

If you have ever listened to a support engineer try to talk someone non-technical through typing out a provisioning URL on that device dialpad you know that it is most certainly one of Dantes levels of hell.

4.0.1 can be set via the web interface.  The have also supported DHCP options for quite a while

Now if only they could get on board with a solution like Innomedia's DMS product which provides out of band management that punches through NAT, THEN you would have a  slam-dunk.

Have you looked at Polycom zero touch provisioning?   It is DMS in the cloud
