RxType=G.729
TxType=G.729
 
RxSize=10 
TxSize=20
 
Avg Jitter=8
Max Jitter=274
 
RxDisc=0
RxLost=1
 
TAC said inbound packet loss could cause the RxSize to be lower.  The
phone didn't show much loss, but jitter was high.

Non matching values should not be a problem as far as I know.  What
codec does the info page show?  How many packets are being lost,
discarded, and what does the phone report as the avg & max jitter?
 
Thanks,
 
Louis

We have some users experiencing choppy voice - I think related to
jitter, but I don't know the actual cause.
 
During an active call I pressed the ? key twice to get the stats.
 
It shows the "RxSize: 10ms" and the "TxSize: 20ms".  I've seen issues
with that before (I think they need to match).  Anyone know how those
parameters get set, and if non-matching values are in fact a problem?
 
Thanks much.
 
Chad
