We have the same problem with our system. Unless you have a solid (not
just high speed) connection between the 2 parties, you're going to get
silence a few times during the call. We had set up a user on a business
comcast high-speed, thinking that would be more than enough. Turned out
though, with most high speed solutions, there is some limited packet
loss and its just to be expected. You internet browsers, etc, would
normally just re-request the packet and move on, but with a stream,
you're out of luck. The only real solution is to have a dedicated T1 or
mpls connection or something like that for perfect quality. We have
solid connections between our offices and haven't had a problem yet.<br>

tcpdump or ethereal (wireshark
now) to capture the stream and then see if there was loss during the
call, just
leave a capture going then get your users to mark out the time at which
they
encountered the silence, compare this to the server time (e.g. their
watch to
the server) to get a time difference, then figure out what time you
need to
look at in the trace.</span></font></p>

<p class="MsoNormal" style="margin-bottom: 12pt;"><font
face="Times New Roman" size="3"><span style="font-size: 12pt;">There
are some remote
extensions connected on this system, and calling long distance is
purely on
voip. These remote extensions also face the same thing, i.e. audio
going blank
for a few seconds, when dialing long distance. So in this case, no PRI
is
involved. Its either the server, or the network. Now I don't know how
to find
out what is it and why? </span></font></p>
