RE: Yealink Attended Transfer vs. Asterisk Attended Transfer
I think Yealink's transfer is based more on pure SIP protocol: basically A Invite B+ B Hold A + B Invite C + B Refer/Notify A + A Invite C
When you dial *2 (or ## for blind transfers) Asterisk (FreePBX) steps in and plays audio file asking for transfer destination and then, after call goes through, it plays the beep file to the receiving party of transfer announcing successful transfer.

There's a feature request to let Yealink phones beep on transfer. I think it can be done.
