It works for me now using Flash key. When updated to the latest CVS and
setting the call parameters in ATA config the unattended transfer works on
ATA too now.

For me the workaround was to define a dial loop in extensions.conf when a
phone is busy (call waiting must be activated).
Then do like that.
- answer the call on ATA
- pres Flash key
- call the final destination
- wait to answer and inform it about the call
- close the phone
- fastbusy on final destination
- close the final destination
- final destination is automatically called by Asterisk from the initial
caller.
- establish the call between them.

All you need is to keep dialing the final destination (in a loop) if busy,
till it rings.

It seems that with the latest CVS update and the correct parameters in ATA
config page this works without the need to do this trick.
Just do like that:
- answer the call on ATA
- pres Flash key
- call the final destination
- wait to answer and inform it about the call
- close the phone
- MOH is stopped and the call is automatically establish between them .
 Tested several times with different configurations:
7960->ATA->ATA
X-Lite->7960->ATA
7960->X-Lite->ATA
ATA->7960->ATA
ATA->ATA->7960

and it works for me now.
