PBX Integration Board User’s Guide

Example

An application uses the dx_dial( ) function to press the “SuperKey” key and

“Display Key 1” for “Yes” on a specified channel on the Dialogic

PBX

Integration Board to display the call forwarding extension. The d42_display( )

function can then be used to retrieve the display data and verify that a call

forwarding extension has not been programmed. The display data is shown

below. The snapshot is a display from an SX-50 PBX with a Superset 420

phone.

Called/Calling Number ID (within the PBX)

If receiving a call on a Dialogic

PBX Integration Board from another

extension, the PBX sends calling number ID data (by default, the extension

number of the telephone placing the call) to the station set between the first

and second rings. The station set processes the data and sends an ID message

to the display. The calling number ID data sent from the PBX to the station set

differs from the calling number ID data presented on the display.

If placing a call to another extension, the called number ID (by default, the

extension of the telephone being called) is shown in the display.

Both the calling and called number IDs can be retrieved using the

d42_gtcallid( ) )function. The d42_gtcallid( ) function retrieves the

called/calling number ID message sent from the PBX to the station set, not the
