thank you for your help! This sounds like good solution. Learning about 
the UserEvent command I recognized that it's probably better if my 
program does not listen for DialEvents but for a custom event, something 
like:

exten => _X.,n,UserEvent(IncomingCall|callerName: 
CALLERID(name)|callerNum: CALLERID(num)|extension: ${EXTEN})

Using the DialEvent my program would display every call, even outgoing 
ones! It should only display incoming calls though. With a custom event 
I can explicitly tell my tool what it should display. Of course, on the 
other hand, there's more diaplan editing to consider.
