This is just the way Polycom does transfers.  Older versions of the
Polycom firmware worked as you describe.  I think it was in 1.6.x where
they changed things to separate blind and attended transfers.  It really
has nothing to do with Asterisk at all.


Understand, but the point was that every SIP device has its own method, and it would be nice if asterisk had a blind/attend transfer feature as described so we are not dependent on the SIP UA vendors to try and normalize the world. If asterisk had the featuer we would not care that every SIP phone does it differently ,there would be one sure method that users could learn that wouild be consistent from device to device.
