caller ID / answering machine software - any recommendations?

[superboyac]

Anyone have any particularly strong recommendations for a caller ID software?  Something that will give a popup or something when a call comes, maybe even keep a log of made calls and duration and other nice features, etc.  Thanks!

i'd also like to hear recommendations of pc answering machine software..
one that seems pretty good is callsoft http://www.toscintl.com/callsoft/
but i haven't really tried many.

One question I have with these software is regarding phone control.  I tried the program A-book, which is an addressbook that can also dial number for you and keep a log of who you called, and the duration.  However, the program doesn't know when you actually hang up...you have to hang up the phone and then click a "hang up" button.  Can these programs automatically detect when you pickup/hangup so you don't really have to do anything yourself?  Is this even possible, or is it not possible to have the modem and the telephone that tightly in sync with each other?  I don't know.
