No, my old phone had the interupted tone and a button lit only on the old phone system plugged into the then separate phone socket.
Since "updating" to digital home phone [as part of updating to Fibre to the Home] and plugging that existing phone into the phone socket on the hub that phone has had no indicator of a message, either tone or light, which is the issue that started this topic.
I've now replaced that old phone with the Essential Digital Home Phone as above.
