performance monitoring</DIV>
<DIV><BR></DIV>I'm currently running asterisk to provide VoIP services to
clients of <BR>the ISP I work for.<BR><BR>I would like to be able to tell if I
am loosing packets and/or are <BR>having other issues with any of the voice
streams, so I can address them <BR>proactively.<BR><BR>I'm not particularly
interested in spending oodles of money buying one <BR>of the commercial
analysis tools. Is there some open source tool (or <BR>something I
can monitor in asterisk) which will tell me if I'm missing <BR>packets or
similar? I realize this will likely be only from the <BR>customer
towards me since I can't really monitor at the customer
end.<BR><BR>-forrest<BR>_______________________________________________<BR>Asterisk-Users
