Assembling an arsenal of VoIP Security Tools to assess various VoIP platforms is quite cumbersome and much different 
from cobbling together  a list of non-commercial network security tools and commercial network security tools.  SiviUS 
is a nice tool but it is not quite complete, as it does not test for H.323 or SIP transformation validation and other 
such features.

Being able to have a product that is capable of producing threshold index on various VoIP measurements including a 
security index on the specific vulnerabilities it checks for would be a great help in accessing a network 
infrastructure migrating to VoIP or reviewing a newly integrated VoIP solution.

Measurement                     Rating                   Index
MOS                               1.0 --> 200.00         1-->5
Delay
Jitter
Loss

Results accumulated by x number of endpoints, and pertinent variables: (RTP, Jitter, RTP, QOS, Frame Compression, 
Payload (GSM, G711, etc), Min calls, Max calls, cycle

Includes a packet capture and playback feature (mostly likely Ethereal with statistical plug-ins)
Can be run from any platform (.tar.gz for U*nix and installshield for Windows especially for those security consultants 
who are far from click here, crank there methodology.
Security Feature checking ability (oscheck for specific VoIP products, using nmap will reveal the underlying operating 
system (sometimes attractive) but one is more interested in what the particular VoIP vendor implemented on top of the 
underlying operating system, or if certain libraries have been removed to avoid the "oops, can be compromised 
warning/red flagging" the hopped up on "RED BULL" or "CROSS YOUR HEART: security consultants tend to point out in the 
fancy long-winded report. 

If a VoIP assessment report is more than 10 pages without a fair amount of self-explanatory graphs, "do not pass GO, 
and start again"

Do take a look at Cain & Abel (www.oxid.it) they have a voip sniffer and it
does work ver well with some implementation.

On top of all that: it is FREE

Have fun

Alo Folks:

Well now we have a audit over VoIP , we need whitepappers, tools ,
links...

the big problem may be are the tools, for example we need "examples"
or "PoC like sniffing over VoIP whith tools tcpdump and Ethereal, how
to convert the traffic to .wav file , Which are the strings over my
shell use tcpdump, opensource and comercial tools.

thanks for all ur help :-)

I think Cain & Abel will have a problem with g723 codec. I've tried 
sniff using Ethereal and it works well. Just that u need some additional 
tools such as JmStudio and rptplay.
