If ID is blocked then you get the "blocked" message. "Out of area" is the "ID unavailable" message.
BTW, if you call an 800 number (or 888, 877, 866 etc), or some other "special" setups, the called party gets the ANI info (similar to Caller ID, but used by the phone company billing system). This is not blockable. And never will be.
Also "blocking" caller ID just means that the info your phone exchange sends to the called party's exchange has the "private" bit set. They still get the name & number info. They just don't pass it on to the called party's phone.
That's how you can use the "call trace" feature and "call last caller" feature on even blocked calls.
"Call trace" just records the Caller ID info at the destination phone company. In most places you have to complain about repeated annoying calls and then the phone co will check that stored info and if it's from the same folks, they'll do something (usually turn it over to the police in the caller's area.
ps. every call I got was from a machine. Either they hung up after two rings, or they just started talking over the answering machine's outgoing message. Said message specifically tells folks to put me on their do not call list.
