Current limitations

This is a beta diagnostic tool, not a guarantee a physical handset will register or that RTP audio paths work. Where the local UDP 5060 source-port registration times out, investigate network handling and device settings.

Starting with v3.4.4, the application checks a signed release feed on launch and offers verified one-click in-place updates. Phone-style UDP 5060 packet capture is built in and requires Wireshark/TShark with Npcap installed on the test PC. Capture files stay local and may contain SIP authentication hashes.
