I have modified der amtsanschließer 33 and the Amtszusatz für den kleinen Klappenschrank for use on Voip adapter.
2 step modidication:
1 witch not is inside the equipment, but just an dialgizmo for konverting rotary dial pulses to touch tones. just plug it in the phone jack.
2 the ringer or indicator draws far to much current for the ATA, so adding a 1 micro Farad capacitor in series with the signal device solves it.
Ofcourse, I have modified a valuable unit, but it may be reversed, and now I may use it . Completely working connection between WWii phones and internet telephony.
