Is it sufficient to use just a Wireshark capture to check the routing of a call in 3CX?

Using just a Wireshark capture to check the routing of a call in 3CX is insufficient because while Wireshark provides in-depth packet-level analysis, it does not offer the broader context needed for comprehensive troubleshooting. Wireshark captures are highly valuable for observing the flow of SIP messages and RTP streams, which are essential for understanding call signaling and media transfer. However, they lack detailed logging and operational information from the 3CX system itself, such as call logs, error messages, and specific configurations that can influence call routing.

To diagnose call routing issues effectively, it is necessary to obtain additional logs from the 3CX system. These logs can provide insights into system events, configuration settings, and call processing that a packet capture alone cannot reveal. For instance, 3CX logs may indicate if there were any registration issues, how the call was routed through the system, any encountered errors, or interactions with third-party systems like gateways or SIP trunks.

In summary, while Wireshark can be a useful tool for analyzing specific network traffic, combining it with 3CX system logs is essential for a thorough examination of call routing and related issues.
