• Identify when 100rel is required vs optional and trace a full negotiation end-to-end.
• Distinguish re-INVITE vs UPDATE and trace mid-dialog offer/answer changes.
• Read any REGISTER flow including Path, Service-Route, and RFC 5626 outbound.
• Follow SUBSCRIBE/NOTIFY for the dialog and message-summary event packages (BLF and MWI).
• Trace blind transfer with REFER and the NOTIFY-with-sipfrag pipeline.
• Trace attended transfer with Replaces and the three-dialog triangle.
• Configure RFC 4028 session timers; diagnose exact-interval call drops.
