hence the OP looking for ways to tune the Livebox output.

Results from more testing are that the base station is detecting the
ring activity and this shows on the handset display as Line 1 ringing,
but there is no audible ring on the DECT handset (the base unit does
not have a ringer AFAIK).

If the Livebox is allowed to ring an old SW Bell cordless and the DECT
is plugged in mid-ring then the DECT handset rings for 2 or 3 rings.

The voltage on the Livebox output measured as Vdc with a digital meter
is 50V normally and when ringing this goes 40V - 0V - 40V in line with
the ring cadence.

A BT line measured in the same was is also at 50V initially but on
ringing flips to -50V. I expect this to be AC but measured it the same
way for consistency.
