On a few calls, at one point the other person could no longer hear me but I could hear them. This was all to the same person who was on a landline. Happened a few times. Once we just hung up and redialed. Other times I stayed on the phone and my voice came back after about ten seconds. Any idea what I could try. I've had it hooked up for less than a day. Have the 202 hooked up to a gigabit switch box in turn connected to the Internet router. I probably don't have it setup correctly. Also I have no QoS on. Also have done no other settings changes other than plug it in allow it to upgrade firmware and start working. Thanks. Jitter is 3 or less with no packet loss and ping at 93 ms.
