I'm looking for a way to
differentiate between regular hangup and dialog timeout.
In both case, the
dialog:end event is called. Do you know which information
can I use in the event route to differentiate between the
two cases?
no embedded mechanism comes in my mind now. For the future, maybe we
can set a specific flag in one of the internal flags fields (dflags
seems appropriate, not being persistent and already exposed via
$dlg() variable).
For now the solution would be to set and avp when you receive a BYE,
before calling dlg_manage() or loose_route(). In event route that
avp should be present if the dialog is terminated is due to a BYE on
the wire and not present if it is internal timeout.
