In order to analyse what this communication between devices contains, a network trace can be requested. Network trace contains whole communication between IP devices over LAN. In this diagram, it is much more convenient to analyze VoIP-traffic for diagnostics (debugging), but it will require knowledge of the principles of the SIP data transmission protocol (Session Initiation Protocol). The Graph Analysis window will appear with a graphical diagram of the VoIP call data exchange. Select a VoIP call and then click the Graph button (or Flow, depending on the version of the program).

The list of VoIP calls shows the following information for each call: The VoIP Calls window opens with a list of VoIP calls. Go to the Statistics menu (or Telephony, depending on the version of the program) > VoIP Calls. sip or rtp to display only a certain type of traffic.Ģ. To filter packets, you can enter a value in the Filter field. Select a SIP or RTP packet from the list (in our example, analyze the RTP traffic). Suppose that during the execution of a VoIP call using Wireshark, network packets were captured and this dump should be analyzed.ġ. Wireshark allows you to analyze the SIP protocol and its RTP traffic. The Wireshark program implements a convenient mechanism for diagnosing (analyzing) VoIP calls, in particular, you can get a graphical diagram of calls and see how data was exchanged. Is there a more convenient and efficient way to debug VoIP using the Wireshark traffic analyzer?

When debugging (diagnosing) an IP telephony service, it is very difficult to analyze VoIP traffic.
