Making Hookflash Transfers

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.

Using Bfv Applications

To configure using the Dialogic® Brooktrout® Configuration Tool (Windows® only):

„Set each port’s Protocol Options to T1 Robbed Bit or Analog.

„Set the Flash Hook Duration between 1 - 500. These are 10ms units.

„Set the Protocol File to the following location for T1 RBS:

C:\Brooktrout\Boston\config\winkstart.lec and for Analog, the protocol file is:

C:\Brooktrout\Boston\config\analog_loopstart_us.lec

„Set the Transfer Variant to Hookflash.

„Set the country_code in BTCall Parameters to 0010 (US). Country codes are listed in:

C:\Brooktrout\Boston\bfv.api\inc\ccode.h

Note: You must be in Advanced Mode in the Brooktrout Configuration

Tool to configure BTCall Parameters.
