Synergy 2150 - does not show names and numbers?
My synergy 2150 worked fine for ages - now it will not display name/number when someone phones (on any of the 3 handsets). It just displays External.
I am not sure if my son may have changed something, but I can't find anything in the user manual to switch it on/off.
Can anyone help?
