Remote hangup does not end both call legs

Trace BYE routing, Contact and Record-Route information across a bridged conversation.

Confirm the symptom

Separate a missing BYE from a user-interface delay. Calls & Reports should show whether both FreeSWITCH legs ended and which side supplied the final hangup cause.

Inspect dialog routing

A re-INVITE or UPDATE can change the media path without changing who must receive the final BYE.

Check Contact, Via, Route and Record-Route values on the established dialog.
Verify that NAT rewriting does not replace a reachable endpoint address with loopback or a private address.
Confirm that the PBX stays in the signaling path for both legs.
