<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am experiencing intermittent garbled speech. Tests show
that jitter, MOS and RTA are present but not bad by any means. (1ms on jitter,
maybe 3ms on deviation, MOS is 4.30 consistent and RTA is less than 20ms). I
should add this is a wireless link but the signal is stable and the AP is not
experiencing any excess waiting due to retransmissions. I was fortunate to
capture some traffic when it was happening this time and don’t seen
anything that strange in the capture. I do have some questions though<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> When the packets are traveling from the direction of the
PBX to the ATA the DSCP is showing as being set as Assured Forwarding. When the
packets are traveling from the ATA back to the PBX it is being showed as Expedited
Forwarding. The garble is heard on the ATA side of the conversation and it is
very intermittent. First of all is the fact that packets are being marked
different in one direction than another odd to anyone? I have administrative
control over the whole link from end to end so my settings should not be being
dropped by anything. Could this be an issue? I also wanted to mention that the
link is not saturated during these times so does that mean that assured
forwarding should be fine?<o:p></o:p></span></font></p>
