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 one of the
following:
• d42_gtcallid( ) function to retrieve the called/calling pair
• d42_gtcallidex( ) function to retrieve the called/calling ID, call type and
reason code
The d42_gtcallid( ) and d42_gtcallidex( ) functions retrieve the called/calling
number ID message sent from the PBX to the station set, not the data sent to
the display. Refer to the Dialogic
®
PBX Integration Software Reference for
more information about using the d42_gtcallid( ) and d42_gtcallidex( )
functions.
