The original one developed a weird fault, replaced with a secondhand one 
for £54

Maybe if it was used on an ISDN line, but I've never used any "converters"

Do Zen fully manage the Fritz!Box, or can you configure it?  Maybe the 
line impedance matching, or ring cadence isn't quite right and confusing

I don't know all the details, but in effect your phone number is

like that.
