I have a Merlin Magix system release 1.5 with a DuVoice voicemail voicemail. I have gone into the DuVoice admin menu and deleted mailboxes at two of the extensions in the Magix. The problem I am having is that the 44xx phones still have Message Waiting Indication lamps lit. I have tried both a phone and system reset and I can't seem to clear the red light. Is there a way in WINSPM that I can force the light to be removed?
