I don't recall the following point being mentioned in the ongoing and
longstanding Caller*ID discussion: If the calling number is displayed,
how long does it remain on the display? Until you pick up the phone?
Until the phone is hung up? For some fixed period and then the display
blanks? Or does the last number continue to be displayed until the
next one (or the message about an unidentifiable number) is shown?

Do any of these displays remember the last "n" numbers shown, so if
you get a string of calls in rapid succession, you can look back
through the history of received numbers to locate, say, the third-last
caller's number? If so, how big is "n" and do they store the
"unidentified" label the same as if it was a number? Are any of these
fancy enough to store the date/time along with the number, or do you
have to hook your own computer or automated logger on the line to get
that degree of service?

Thanks for info!
