... and answer machine is other program, available in -dev if I remember correctly If not, there is no such a program, and everyone is encouraged to write one.

I basically agree with You - except that I (or linux, lately) don't have anything against more available options, if only they're pure optional (can be reliably turned on/off one by one), and turned off option doesn't increase resources usage, compared to version without such features at all.

Long story short, you can incorporate answering machine to this program, but it should be still possible to use it as call-blocker only, without increased CPU/RAM/battery/whatever drain. Of course app passive "HD" space requirement increase is perfectly tolerable (to sane levels).

// Edit

nice catch on psychological aspects. I also agree. that best way (by meritocratic terms) is just to automatically hang-up calls, and all pre-recorded "messages" are just ego boosters for blocker. I don't have anything against implementing this option, if someone is willing to volunteer her/his time on doing so, but for me, it's pure waste of coding time.

OK, I see at least one use for automatically (and silently) picking up calls, they playing something pre-recorder message - this way, we can make entity calling us (be it dumnb-lottery or whatever) wasting money (since call is successfully picked up), without any effect. Not to mention playing specially audio sample with insanely boosted volume lvl - with a little luck, it can blow someone ear or at least speaker )
