Why and how do I receive zero second voicemails?


    After months long health insurance scammer calls, I began to screen all my incoming calls with unknown numbers; especially if they are out of my state and with matching first 3 digits. Fortunately those calls decreasing in numbers by each day.


    The new thing now is though some unknown numbers, and some "Scam Likely" labeled callers begun to leave zero second voicemails.


    What's that? How is it possible to leave zero second voicemails?


    I'd imagine all things been digital the T-Mobile systems would be able to filter them out. But that's not the case. Not yet anyways.


    Does this happen to anyone else?

        Hmm, have you ever answered these calls to see if they're coming from an automated system? I pretty sure this has happened to me before but I was getting a 1 second voicemail. They only thing I can think of is it's a automated calling system disconnecting shortly after the voicemail starts to record.

          Hi there.


          Just checking in to see if you've answered these calls or know if these are coming from automated systems?

              I now get these just about daily. I've answered one or two by mistake, and can confirm they are indeed robocalls. The routine is reliable: an unknown number from my area code rings, I decline it, 15 seconds later a voicemail of one second with no audio whatsoever appears on my iphone.


              Regardless of origin, it doesn’t make sense for the system to forward a voicemail notification for a one second long message that contains no audio content. Either a minimum time (can anyone relay anything meaningful in under, say...3 seconds?) or audio peak level should by themselves disqualify these as voicemails. I emphatically urge T-mobile (and/or apple, I suppose, since this may be specific to Visual Voicemail) to remedy this; I can't be alone in nearing the end of my patience for it
