Introduction

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 will not be available. Please see WEP/WPA Keys and Understanding WPA Decryption for more information.
