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.
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
a hookflash (wink) and initiate dial tone recall to transfer a call
using a single channel.
