have you installed the most recent version? the most recent version addressed the bug i mention in the previous post.

Usually the problem is at the list? to test remove the blacklist.txt and restart the callerx, then get another phone to test it.

edit.

seems like you're using old version, update it.

your suggestions is cool but then again what happen if you are talking on the phone with someone and blocked caller call, the phone would have to switch the line and pick it up and play the message. you don't want that...
