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.

Did you try swapping phone and PC to find out if the problem lies with switchport rater than switch ?
Did you try power of/on the switch?
Is all firmware up to date?

A similar discussion perhaps is going on in:

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

You wont believe this. My schoolboy error, I swapped the switch ports, patch panel port, ethernet converter and the switch itself, in all cases. Only the PC got an address. All the while I was not swapping the ETHERNET CABLE! Although the phone was coming on and displaying its progress then being stuck on DHCP Discovery I had not at any one point thought they'd be something wrong with the cable itself!!
