That does not sound right at all. The difference between the two Time=
values should have been 10 (milliseconds).
Did you reboot the Sipura after making the change? There are some values
in the Sipura that don't take effect until after the next reboot; I don't
have a clue whether this
Rich - thanks! Glad I am not the only one seeing this :)
Would be very interested in your results. No problems that I see yet
with these settings.

Actually - jitter does not seem to be the issue (sound is not garbled
and does not drop out, it was just very low and fuzzy/staticy when
not set to 10 ms).
It is weird that I have to drop to 10ms, but I have tested some more

Actually the SPA-2100 supports 2 g729 channels which is why I bought
it. Unfortunately, the call quality is just as poor on the 2100 as it
is on the 2000.

Next thing I would check are the de-jitter buffers if possible on the Sipura, or jitter in general.
Do you have control of the PSTN gateway ? Measure the jitter on ingress to the gateway. You can do this crudely by using Ethereal

FYI - Seems the latest firmware in conjunction with changing the
packet size to 10ms improved the call quality to usable. The Cisco
7960 is stell superior, but now at least the SPA-2100 is acceptable

Is anyone out there having any luck with the SPA-2000 or SPA-2100

If this has been covered before - I appologize.
We use some Sipura SPA-2000's with the g711 codec and all seems fine
(except for the occasional failure to register errors in my asterisk
logs - but I will save that for another post).
g711 call quality is on par with our Cisco 7960's. However,
