Not only that, but even when the landline has Caller ID, there's no guarantee that the numbers you see have any relation to who is actually calling you. Even worse, landlines charge you extra for the privilege of inaccurate Caller ID. When I finally ditched my landline and moved it over to VoIP, AT&T's monthly fee for CID was greater than the entire monthly cost of my VoIP provider. A shame, since if there was one thing the landline phone network was, it was reliable - in a way that cable can't even hope to match. Too bad that it got to be reliable for scammers as well.
