How do i prevent a Tracfone from going to voice mail when there is no cell reception? I live in an area with poor cell reception. If the call goes right to voice mail, then the call will never make it to the OBi device, right? The Tracfone I have uses Verizon as the carrier. I am using Google Voice. I looked at the other posts that were relative, but there didn't seem to be a clear answer.
