Why is the light not coming on with a new Voice Mail Message?

tone, the Set Audio option has been used to set up the phone for headset

use; press Headset

Check that the leg stands have been properly snapped into place. Since the legs can be oriented in two different ways and in two different positions to offer four different phone viewing angles, check that both legs are oriented in the same direction and in the same position on either side of the phone.
