4.7.8. 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 programmable 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

transfer is performed, your application can implement call progress analysis
and called/calling number ID to intelligently control where the call is routed
and what type of message is played if the called extension is busy or does not
