Description

Captures the fact of marshaling a call that has the purpose of spoofing a caller for one of the arms of another existing dialog (SIP request INVITE with the Replaces header in addition to the header Referred-By).

The event links the new challenge (future dialog) created by the substitution transfer to the dialog it aims to substitute.

Using the example of the case [A→B, B→C, B refer A, A→C] places the dialog information in the dialog A→C B→C.
