I've got a Mitel phone that is stuck in DHCP DISCOVERY. It is located in another building. That building is connected to the main building with a fibre link using a fast ethernet media converter The network map is shown below.

I have tried other phones and they dont work however if I take the phone back into the office it works fine.

I've called Mitel themselves and they have no idea what could be causing this. HP advised to try turning spanning tree off but this is all to no avail. PLease Help

Other Info

The only firewall we have is in the perimeter network and I dont see how it would affect this. The HP ProCurve has no VLANS configured except for the default one.

I have swapped the phone and PC, the PC manages to get an IP address but the phone stays in DHCP DISCOVERY, I have upgraded the firmware to 1.04, released 2007 (SRW208P) and reset all settings to no avail. Both switched have been power cycled
