Something like this should work (where BBBB is a caller ID digit string)

; Pay attention to the placement of dollar signs and brackets
exten => 1234,1,GotoIf($[${CALLERID(num)} = BBBB]?3:2)
exten => 1234,2,Macro(dialswitch, ${EXTEN})	; ok, go to switch
exten => 1234,3,Answer
exten => 1234,4,Playback(tt-weasels)		; bad guy
exten => 1234,5,Wait(1)
exten => 1234,6,Hangup
