4. PBX Systems
The Dialogic® PBX Integration Board can retrieve the information on its
alphanumeric display using the d42_display( ) function. The function places
the display data (48 bytes) in an application buffer. Refer to the Dialogic®
PBX Integration Software Reference for more information about using the
d42_display( ) function.
Example
An application uses the dx_dial( ) function and the appropriate dial string to
press keys to dial extension number 1045. Then, the d42_display( ) function
is used to retrieve the display data and place it in an application buffer (shown
below). The information for the top row (first 24 characters) of the display is
checked. Data in bytes 00 through 05 indicate that extension 1045 is being
dialed.

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.
