4.3.6. Transferring a Call

The Dialogic

PBX Integration Board can transfer calls using the dx_dial( )

function. By using the dx_dial( ) function and the appropriate dial string, the
PBX Integration Board can transfer a call to any extension connected to the
switch. Refer to the Dialogic

PBX Integration Software Reference for more

information about dialing programming keys.

The Dialogic

PBX Integration Board can perform both supervised and blind

transfers (refer to Sections

2.1. Supervised Call Transfer

and

2.2. Blind Call

Transfer

). If a blind transfer is performed, the PBX controls where the call is

routed if the extension is busy or does not answer. If a supervised transfer is
performed, your application can implement call progress analysis (CPA) and
called/calling number ID to intelligently control where the call is routed (by
completing or aborting the transfer) and what type of message is played if the
call extension is busy or does not answer. Because of this capability,
supervised transfer is a comparatively preferred method.

Initiating a Transfer

Once in a connected call, you can initiate a transfer using dx_dial(&,)
where & acts as a key press of the transfer key and is the PBX
extension to which you are transferring the call.

Completing a Transfer

To complete a call (supervised or blind) simply go on-hook using the
dx_sethook( ) function.
