asterisk users - Oct 2003 - Announced Call Transfer

I know this topic has been done before but I cant find an answer for it 
anywhere.

I have Grandstream phones running with my Asterisk server.

Is there anyway to do announced transfers with these phones?

i.e. A is talking to B, A then presses a key to initiate transfer, calls C, 
tells C that B is on the phone.  Then A hangs up and C is connected to B.

No, its can't be done with the GS phones, as a work around you could put 
B on hold then call C tell them about B then go back to B and blind 
transfer to C..
