Is it head phones or hand set ?

The red light you see on the handset is when some one leave a voice massage and we call it MWI message waiting indicator.

That’s mwi which gets turned on when some one drop a voicemail. You cannot use that a notification for missed call.

if you clear all mailbox the mwi light will get turned off.
