I have an iPhone 6+ with Verizon as my carrier. When I got to Phone > Voicemail I see a message. Usually I can click the message and it will automatically start playing the message. However, with this message the play button is grayed out. This doesn't happen with other messages. I checked my Deleted Messages and can still play back all those old voicemails.
I can see there is 1:09 minute long of a message for August 15th but my only option looks like I can Delete. The phone number is not from my contacts, but its a number I recognize in California where I have family.
How can I listen to this voicemail?
PS I noticed a difference between this problematic voicemail says -1:09 (negative time?) while other ones in the past show 0:10 or 0:43 seconds. What's with that?
