It has nothing to do with the phone its just maybe the voice mail resetting because you call right back try calling 2 or 3 minutes later if not maybe the person doesn't feel like taking your call or anyones

it means the person picked up the phone but didnt say ne thing and when u called back he/she either turned it off,it died, or was on the phone wid someone else.

Probably the person you were trying to call cancelled your call.
