[Freeswitch-users] Activating MWI from a Mitel 3300

I have a freeswitch connecting to a Mitel 3300 via sip trunks. We are using the Mitel embedded voice mail. I'm trying to figure out how to light the MWI light on sets running off of the freeswitch. Is it possible to light a MWI across the SIP trunks? Does anyone have suggestions on how to proceed to figure out how to do this? Dryaquaman
