Hello - at one of out sites we have the 3900 series phones. Have had several users tell me when they depress the mute key and the light is on - that they can still be heard. I sort of thought it was user error until I saw it happen. The mute light is on - but the party on the other end can still hear you. We had to depress the mute key several times before it actaully was mute.
Thanks for any help!
