[Freeswitch-users] IAX Transfer support

I have been using freeswitch for over a year and I love all of the features, extensibility etc. Recently one of the clients wanted to use a IAX client and call from the IAX client works fine but there was one feature requested by my client that did not work. The feature is the "IAX Transfer" and I see the Transfer message come through by turning up debugging in the iax.conf file but freeswitch does not do anything with it. What is the current status of IAX support on freeswitch?
