Making Hookflash Transfers
You can make hookflash call transfers using either the Bfv- level
API or BSMI-level API. There are two types of hookflash transfers:
Analog loop start signaling
Transfers using loop start signaling commonly use hookflash.
Transfers using loop start signaling commonly use hookflash.
Hookflash allows for both blind and attended transfers using the
same channel. In a blind transfer, the application drops out of the
call before the transfer completes. In an attended transfer, the
application waits until the call is successfully connected to a new
number before completing the transfer.
T1 Robbed Bit signaling
T1 Robbed Bit hookflash transfers use E&M signaling to generate
T1 Robbed Bit hookflash transfers use E&M signaling to generate
a hookflash (wink) and initiate dial tone recall to transfer a call
using a single channel.
