Note: The
VoIP analysis module is only available to VoIP license users or
evaluation version users who selected VoIP evaluation mode.
VoIP analyzer is a
built-in CommView module that is suited for real-time capturing and
analyzing Internet telephony (VoIP) events, such as call flow,
signaling sessions, registrations, media streams, errors, etc. By
visualizing this data and assessing voice quality, this tool helps
you boost productivity in debugging VoIP networks, software, and
hardware. CommView's VoIP analyzer supports SIP
2.0 and H.323
signaling
protocols and RTP
2.0 media streams and many
widespread codecs. In addition to real-time analysis, the analyzer
can be used for post-capture import and analysis of capture logs in
a number of formats (e.g. Tcpdump, EtherPeek, etc.).
If your WLAN uses WEP or
WPA encryption, you must configure the WEP or WPA keys correctly to
be able to decrypt network traffic; otherwise, VoIP analysis won't
be available. Please see
WEP/WPA Keys
and
Understanding WPA
Decryption for more
information.
