Analyze call quality data

For Wireshark versions 1.0 and 1.1:
  1. Unzip the downloaded call quality data file.
  2. Two types (info file and a monitor file) of files are captured in the call quality data file. Open the monitor file in Wireshark.
  3. Wireshark will show the trace as UDP. To convert UDP trace to RTP:
    1. Right-click a packet and select Decode As.
    2. Set to RTP.

    Perform the above procedure for the reverse stream also.

  4. Once all packets are displayed as RTP, select Telephony > RTP > Stream Analysis.

    VQ analysis with Jitter and bandwidth data is displayed.



For Wireshark version 3.2.2:

Use the following procedure to decode UDP packet into RTP.
  1. Wireshark will show the trace as UDP. We need to convert this into RTP, right click on a packet and select decode as option.

  2. Decode As window prompt will open. Set the following options to decode the packet in RTP and select OK:
    • Field: UDP Port
    • Value: 12002 Port Number(DST Port)
    • Type: Integer, base 10
    • Default: none
    • Current: RTP

  3. Once all packets are displayed as RTP select Telephony > RTP > Stream Analysis.
  4. This will then open a VQ analysis which shows Jitter and bandwidth.
