This issue has probably been resolved now by many / most of you, but I outsourced my grievance to a very helpful small independent vintage telephone specialist company who weren’t aware of the problem. I sent them my Beocom 2 Mk1, they disassembled it to ascertain the issue and how the B&O design was supposed to work, then designed and built me a small box (like a plug in adapter for between the Beocom 2 and the wall socket). It works perfectly alongside my Panasonic DECT phones within the home.

The cost charges was very small compared to the number of hours I’d spent pondering over various threads on the issue. Very happy with the solution they’d resolved, and it’s been working faultlessly for about 9 months now.
