RE: Unable to obtain IP Address over DHCP
I encountered this with a switch that had a few ports configured not to use RapidSTP. Without RapidSTP it took about 30 seconds for the link to come up and so as a result it timed out and DHCP timed out before the link as up. Enabling it fixed it right up.

Might want to double check both that the switches have RapidSTP enabled and all the ports that have phones plugged into them have RapidSTP enabled.

I do agree it is annoying that it is pretty much required but in fairness users and Windows expects it these days as well - Windows will time out reconnecting network shares as well if RapidSTP isn't enabled.
