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

Hi,

> What are the there legal ramifications to this?  While I like to think that "it's my network, I'll do what I want to measure its performance", I *think* that sniffing voice traffic without consent is considered wiretapping.  IANAL, but it would behoove you to get a consent form from your customer prior to taking this route, just in case.

dependsw what country you are in, why you are 'sniffing' and
how you are sniffing. if you are using an automated process to
keep measurements and are not looking at anything such as the payload
you have already removed a whole heap of issues. one would hope that
the voice traffic was encrypted by default so there was no 'wire-tapping'
argument (boy, I've had fun demonstrating why encryption should be
turned on ('but I'm on a private switched network!' they scream) )
finally, if you have no other indications of _who_ or _where_ the
IP addresses in src/dst are then thats another lot of privacy baggage
dumped.

the general concensus is that standard automated monitoring of network
performance with no tie to ownership or data within packets is fair game.

PS IANAL.
