Use the phone network traffic data to debug phone registration and call-related issues. Use the phone web interface to capture the real-time network traffic of the phone. The phone sends the network traffic data to the computer from which you launch the phone web interface. When you start the report to capture the network traffic, the phone sends the traffic data to the browser and creates the final .pcap file on your computer. Depending on your browser setting for the download location, the phone saves the .pcap file after you stop the report. You can also obtain network traffic when your phone is on an active Wi-Fi connection. The packet capture file has data only if there is network traffic while you run the report.
