+1 on wireshark/packet tracing
I actually wrote a 'interface' around gulp (a packet grabber) and pcapmerge
to allow our support folk to selectivly pull traces from a bunch of passive
taps in our network.
Initially I was also capturing RTP streams, however, due to legal concerns, I
now only turn up individual filters for RTP.
however, all signalling still does get caught.. makes it really easy to retroactively
look for a packet trace when the customer calls in an hour later with an issue.
it all currently writes to a 16 TB dedicated EMC SAN.
I'm getting ready to release my package as open source... internally I call it the
'MegaSniffer'... however, not really sure what to name it going forward.
there's been lots of ideas for go-forward development, including auto-parsing the signalling
data (sip ladder diagrams, etc)... however, the way it is right now has been used extensively
by our support folk.
