I have one router that has one way GOOD MOS, from the gateway/HUB to the router, but from the router to the gateway/HUB, it is poor. The MOS is 2.2, the jitter is 3.0 ms, Latency 7.0ms and packet loss 0%. The reverse call path is 4.34, 3ms, 7ms and 0%. Pings are good, so I am quite puzzled why I am seeing such poor MOS.
