It primarily depends on how the information is entered into the LIDB. Cellular numbers rarely have names associated with them, but landlines almost always do.
2-line Caller ID boxes used to exist, but, with all but the most inexpensive telephones now sporting Caller ID displays, stand alone boxes have all but disappeared.
At this point, I'm surprised that the RBOCS still offer dial tone without Caller ID. I suppose alarm systems have no use for Caller ID, but, from a residential perspective, include Caller ID with even the most basic service.
