asterisk users - Jul 2004 - qudBRI and transfering calls with the latest RC2.

I'm trying the latest bri 0.1.0 RC2 drivers. 
In announce I see implementation of so long waited Transfer feature.
But I can't make it work. 
When the person who is making transfer after talking with second party press 
"R" second time to establish 3 way call 
the person to which call supposed to be transfered being disconnected.

Any ideas whats wrong?

Thanks,
Dmitry
