When you say 'binaural' do you mean each headset receiver is connected to something different? The 'new' type of inset receiver in the Statesman or Ambassador has an impedance of typically 462 Ohms at 1kHz so is a lot higher than the traditional kind. Are you replacing the handset receiver inset with the headset or are you planning on running the handset as well?
You could use a matching transformer (or transformers) to adjust the impedance to your headset, but you'd need to find them small enough to fit in your phone.
