What action should follow starting a Wireshark capture to troubleshoot phone registration issues?

When troubleshooting phone registration issues after starting a Wireshark capture, the most logical next step is to analyze the captured data. This analysis helps identify potential problems in the SIP (Session Initiation Protocol) communication between the phone and the 3CX server. By examining the packets, you can see whether the phone is sending registration requests and if the server is responding appropriately. This will provide insights into whether there are network issues, misconfigurations, or firewall settings that are blocking communication.

Rebooting the phone, while it can sometimes help, is not a systematic method for troubleshooting and does not provide any data or insights into the root cause of registration issues. It could interrupt the capture you just started, preventing you from gathering valuable information. Displaying logs on the phone may provide some information specific to that device, but without the broader network perspective and packet details that Wireshark offers, it would be less effective for diagnosing issues that may stem from external factors like network conditions or server configurations.

In this context, the focus is on using the tools at your disposal, like Wireshark, to gather comprehensive data that can guide your troubleshooting process more effectively than relying on a simple device reboot.
