Check the "Telephone Headgear" link at

It looks promising. I have not tried that. 

Other way to do conversion could be to take a telephone 
that has a removable cord between the handset and base unit. 
Then make a small adapter from headset connector to 
headset. Somethign like what is done at

Note: There are differences in the implementations 
of handset interface from base unit to handset in different 
telephones.
