T3 Tabletop not ringing

[me23]

Tried to intercom my wife in her office the other day and she said she never heard it ring.  So I checked it out and she was right, I cant get it to ring.  The ringer volume and speaker volume is turned up to 100%.  I turned off all auto answer, etc.  When I page it, the screen of gray microphone with ignore and answer show but no sound of ringing.  The speaker is good because I can hear audio if I do answer it.  I rebooted it and refreshed the navigators in composer.   I'm at a loss here.
