[Freeswitch-users] Refer with replaces - how to configure to support

[Magnus]

Hello All,
 I had hoped that this would be straightforward in terms of asking if FS can support Refer with replaces support, but perhaps I'm asking in the wrong way,  hence can anyone confirm that FS supports RFC3515, RFC3892, RFC589 ? I see all mentioned in FS specifications page, but yet to stumble into how it could/should be configured - Any/all tips welcome.  

Regards
Magnus
