A few years ago I posted a how to guide to getting Mitel dual mode phones into SIP mode and registering them on your SIP server. While my configuration on that particular job used the programable keys on the phone, there was no call for Busy Lamps.
Last week I was asked to use these phones and get the BLF working. I scoured the Internet and having patched together a couple of resources managed to get them to work.
On these phones you have the <User> tag section to define your user and also the <pkDescription> section to define the keys. Just as your phone wont work for you without both the user and the key setup, so the busy lamps wont work without a modification in both of those sections.
In the <User> section you need to define the users you want to subscribe to BLF updates for. User the BLFGroup="" to do this. Fill the quotes with a comma separated list of extensions to monitor . Then in the <pkDescription> section you define a key as Fea="27"
The below file is the MN_userID.cfg file in my TFTP server. Note how I use the BLFGroup= to setup a subscription for 1050, then in the key section, key 27 (third up from bottom) is the BLF key for 1050
<Parameter Model="5312">

Have a play, it worked for me.
