I have a PSTN line that rings an extension.  If that extension is unanswered, it is set to forward to a ring group.  If the call still goes unanswered, then voicemail kicks in, for the ring group extension. Fine.  However, there is no indication at any phone that there is a voice mail message.  Nobody knows that there is a message waiting. Shouldn't the 520x light the mesage lamp on one or all of the group members?
