To return to normal conversation, press and release M again.
NOTE: Switching from handset to speakerphone or from speakerphone to
handset also cancels Mute.

lines are lit during a conference call.

Press the Line button of the remaining call to disconnect the other line and
eliminate the dial tone.
NOTE: Under certain circumstances, the far-end parties on a conference
call may not hear one another clearly.
