Some phones have jack on the side of the phone. If it does not, you will need a standard telephone headset with amplifier. You will need a handset button (634) programmed on the phone. Then in programing Flash 50 button 4 you will need to disable speakerphone. Flash 50 button 18 determines the headset type: 0-is amplified unit plugged into handset cord, 1-is 2.5mm jack on side of phone,

To use handset, press handset button so it is lit, use on off to answer calls with the handset.

this is done in system programming.

If you are using the headset jack on the phone, a headset key needs to be programmed on the the phone. You can do this in program mode and make a line key a headset key. Otherwise you must connect it through the handset. ldtsnj.com

I have the 8 button phone and if you hook up your headset the right way you just have to press the line/feature access key all the way to the right instead of picking up the receiver. Keep the headset on all the time and just press that button to answer or hang up the calls. It works great! ( I have the Dterm80 telephone)

Do you have a headset button programmed on your phone?

headset key has to be programmed on a key for it to work properly

For the DTU phone on an NEC Elite system:
Memory Block 4-12
put in the port number and the Lkey of the extension you want to make a headset key.
Programmin on a 16button phone, Lkey 11 needs to be lit and will display H SET to verify.

For the DTP phone, it is generally on an NEC 2000, which is entirely different.
