Yes.

Something similar to this will work (untested, possibly with syntax errors, but gives the idea):

	exten => s,1,NoOp(Inbound call from callerID $CALLERID(num))
	exten => s,n,Hangup

The 'Hangup' will simply tell the FXS box (which you've used to terminate the line) that Asterisk isn't accepting the call.

One problem could be the FXS box re-inviting Asterisk over and over (causing duplicate NoOp logs), but you could add a Wait in there for 2-3 minutes before 'Hangup'. Not many calls would ring for more than 2-3 minutes. In fact the PSTN may limit the number of rings (I have a feeling here in NZ it's about 250 rings or so).

	exten => s,1,NoOp(Inbound call from callerID $CALLERID(num))
	exten => s,n,Wait(180)
	exten => s,n,Hangup
