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:12.0pt'><font size=3
face="Times New Roman"><span style='font-size:12.0pt'>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>
