[c-nsp] Opensource tool to measure Jitter for VoIP

[Bryan Campbell]

You cannot measure VOIP (sip) jitter using ICMP tools.  You will only
isolate false positives when the ICMP is not doing well.

Route or mirror the customers traffic trough a monitoring station.  Run
tcpdump or Wireshark to get a pcap file that contains traffic of
interest.  Wash the pcap file through the Wireshark VOIP analysis tool
to find your jitter.  It is a standard tool in Wireshark.

If you can't find jitter in this manner, it cannot be found.  If it
cannot be found, it doesn't exist.
