<p class=MsoNormal><span lang=EN-US>Some customers need more attention, and
need more fault finding. I thought of adding some sort of customer tracer to my
OpenSIPS config. Basically, IF a customer’s-debug-flag is ON: all SIP
messages except REGISTER get recorded, both coming in to OpenSIPS and just
before leaving OpenSIPS.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Pretty much as using tcpdump on a selected
user. I believe the solution would be much more elegant if contained in
OpenSIPS.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Is this just simply crazy idea? Has it been
done before? Will it cost too much in processing power? Should I instead do
some clever selective tcpdump?<o:p></o:p></span></p>
