Checked these and they all seemed to be correctly set. Still isn't working. But we were only using the feature for a few groups and it was only to forward the group to Voicemail at the end of the day or when no one was in, so I just changed the settings to have it go straight to Voicemail at night. I'll see if the diagnostic feature works for checking to see if the hardware is malfunctioning. But for now I think I have a workable solution in place now.
