a few phonse are showing mwi lights but after clearing messages the light will remain on. How do I clear the lights? Thanks
Ginger has given you some great info here,as always, (5 points for this detailed answer Ginger :)
The Message Lamp on the phone is usually associated with the main line (Line button 1) on the Telephone, so if you Press line button 1 and dial the MWI OFF number (like 2600 in my first example) the Red lamp will extinguish.
Hope this helps!
