FreeSWITCH Version 1.0.trunk (10481)

No difference with just "deflect"--the call does not clear when the REFER is 
completed, nor are there any events published on the outbound socket vis-a-vis 
the NOTIFYs.

The behavior that would work the best for me would be an event with the final 
response (success or fail), so my app can wait for it and know if it can hang up 
the call (on success), or it needs to do something else on failure.

An event on each and every NOTIFY would be acceptable as well (not the just the final), 
but that would probably push some of the SIPishness of parsing the fragments into 
the application.

Alas, that one caused a core dump:
