So you can convert from line level audio to OHIS. Both directions:

Line Level User Adapter

Takes mic audio from Line level, pads it down to mic level, blocks DC.
Takes headphone audio from OHIS, and just patches it through to line level.

Line Level Radio Adapter

Takes mic audio from OHIS, blocks DC, amplifies it up to Line Level.
Takes headphone audio from Line Level, runs it through a headphone amp.

Bonus points for including DC isolation: with audio transformers, or caps, or similar.
