Agreed!  In regular PBX telephony there is no technological difference
between a blind transfer and an attended/supervised transfer.  As far as
the generic PBX or key system is concerned, a transfer is a transfer.
The only thing the differentiates the blind from the attended is the
BEHAVIOR of the person initiating the transfer.

HOWEVER, with the various types of SIP phones, firmware revs, etc.,
there are some issues.  When the OP gives us the details on his exact
config hopefully we'll be able to point him in the right direction.
