Message-ID: <email@example.com> For about a year, now, sporadically, our little ILEC-supplied, stand-alone, Caller-ID box has taken to flashing an amber "Message Waiting" light after an unanswered inbound call has stopped ringing. Rarely -- maybe once or twice a month. More usually it turns on a steady, green, "New Caller-ID info" light instead. (Same LED lamp for both lights -- a 2-color device.) We have no ILEC-supplied voice mail, so there's no actual message awaiting us. And going off-hook long enough to hear 5-10 seconds worth of dial tone is enough to make that "Message Waiting" lamp turn off. So, my question is: what sorts of signal on the line might be causing that lamp to light? or to extinguish? TIA for any known facts. Cheers, tlvp -- Avant de repondre, jeter la poubelle, SVP.

There are specific tone signals to turn the message waiting light on and off. R's, John
