If you do the selection wether a call is offnet or not via a "dialout prefix"
(for example "0" + the outward number to call), then the following might
help:

exten => _0.,1,Set(CALLERID(name)=${CALLERID(num)})
exten => _0.,2,Dial(Zap/blahblubb,${EXTEN:1})

This would set the CALLERID-name to the number, e.g. 1231.
If you need to map other numbers, you could e.g. use the Asterisk DB()
feature. From the console, put the external numbers to use:
database put mapexternal 1231 9811231
database put mapexternal 1232 9442332
(you get the point). Then

exten => _0.,1,Set(CALLERID(num)=${DB(mapexternal/${CALLERID(num)})})
exten => _0.,2,Set(CALLERID(name)=${CALLERID(num)})
exten => _0.,3,Dial(Zap/blahblubb,${EXTEN:1})

would map the internal CALLERID to an externally valid number. Be sure
to specify the external number in a form that your PSTN line will accept
(e.g. in Germany, ISDN numbers have to be specified without area code).
