Ive got a nokia E63, has been working fine, but yesterday could not phone out on it, it rings another phone but i cant hear it my end or hear any one speak help.....

The business class phones from nokia have a low sounding ear speaker to aid at confidential business calls . if you think the sound is not at all audible use your warranty , first try in a room if you can hear , or try increasing the volume by pressing the volume keys on the side of your phone .
