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 
data sent to the display. Refer to the Dialogic

Reference for more information about using d42_gtcallid( ) function.
