Is it possible to adjust ring cadence, voltages etc on an Orange
livebox ?

My neighbour's won't ring a 2-line DECT phone although the phone shows
it is ringing on the handset. BT landline calls to the 2-line DECT
phone work fine. RJ11-BT adaptor with ring capacitor and ADSL
microfilter used on Livebox output makes a SWBell phone ring but not
the DECT.
