GN Netcom EHS1 Electronic Hookswitch

Never miss another call. Use the EHS1 and answer the phone remotely.
A built-in ringer alerts you to incoming calls.
Then, just activate your headset and your handset is electronically
"taken off hook" for you to field the call. And when you're through,
simply switch off your headset and the EHS1 hangs up the phone. Please
call or email to see if your telephone is compatible with this product!
