Hi,

Maybe this is not the right place to post this message, and maybe this
is not any "fresh" new, but, here it goes.
I received this e-mail today, and i'm forwarding it to this mailing list.

The Bad News:

| VoIPong is a utility which detects all Voice Over IP calls on a
| pipeline, and for those which are G711 encoded, dumps actual
| conversation to seperate wave files. It supports SIP, H323, Cisco's
|  Skinny Client Protocol, RTP and RTCP.
|
| It's been written in C language for performance reasons, proved to
| be running on Solaris, Linux and FreeBSD; though it's thought to
| compile and run on other platforms as well.
|
| On a 45 Mbit/sec actual network traffic, it's been verified that
| VoIPong successfully detected all VoIP gateways and the VoIP calls.
|  CPU utilization during the run has been found ranging between 66%
| - 80% on a 256MB RAM, Celeron 1700 Mhz Toshiba notebook.
