This process will work as long as your lines are set for key ring by the installing technician.

While your handset is on hook press # 725, you will notice your line keys will light up, most likely they will be RED if your phone isn’t ringing on incoming calls. Tap each line key until they turn solid GREEN and the display reads “ALWAYS RING”.

If you want to make lines stop ringing tap each line key until they turn solid RED.

When you are finished making your changes press the speaker key until you exit programming.

By default the indicator light at the top right corner of the NEC DSX 22B Display telephone and the NEC DSX 34B Display telephone will flash whenever there are new caller ID records (logs) at that extension.  This sometimes causes confusion because this is also the light that flashes when you have new messages in your mailbox.

This feature can be disabled by removing the Caller ID Alert Lamp feature from the class of service.  When using the keyset for programming this can be found in 1404-06: Caller ID Alert Lamp
