I can't believe she was ever left alone to make a phone call.
Besides that, if our FBI was handed the voice mail, they would have deciphered the message by now. Even where it came from.

She may have been left alone if Joran thought she was asleep/unconscious.
Unless she was in the trunk of a car . . .
Did Greta really say on the view that the body has been found?
"I can't believe she was ever left alone to make a phone call."
Could've been left alone bcse she was still unconscious from the drug, then came to and grabbed a phone to call for help.
Plus leave her ALONE with a PHONE.
