I just got this update after waiting three days with no reply from the support folks:I know that some of you have pointed out your petition responses as not being helpful for this issue. Keep in mind that the problem is occuring on the server side and its not something that tech support can help you fix by changing settings on your computer. In some cases, players might have success updating firmware or changing other settings, but this is not in any means our solution to the problem.
I do have an update for the voice chat service issue you are experiencing. Recently the voice chat service we use called Vivox had an update for their service. Basically what we know so far is that the update that they had made the packets of information coming through your router are to big for the router to handle. We are aware of the issue and are currently looking for solutions to the issue, we are working with Vivox to see if this issue can be resolved on our end. I do apologize for the frustration this must cause you, I do guarantee that we will find a solution and fix this issue. In the mean time let me know if there is anything we can do for you? Once again I apologize for the inconvenience this is causing, we will inform you once we have a resolution. Please let me know if there is anything else I can do for you at this time?
So it seems that vivox is the cause according to Sony. Do we believe them?!?
Tech support and customer service is trying to be as helpful as possible by providing suggestions, but in many cases there might not be anything you can do until we fix the problem on our end. Again, not everyone is experiencing the problem, but this doesn't mean its something wrong with your computer or router.
We're still working with Vivox on resolving the remaining issues and hope to have it done very soon. I'm in contact with them every day to get a status update and they've assured me that they are reviewing logs that some of you have provided and working on the problem. Unfortunately I cannot provide you with a timeframe right now. As soon as I have more details, I'll let you know.
