� Blind call transfer
A blind transfer allows the user to transfer a call without speaking with the receiver of
the transferred call. For the user, the call ends as soon as the transfer target's phone
number is dialed. The underlying mechanism is the user's phone sends the contact
information for the transfer target to the phone of the other party on the call. The
information is carried in a signaling message. When the message is sent, the user's
phone is dropped from the call and the other party's phone automatically dials the
transfer target.
