Is it reliable?
With BT, when presented by the caller the telephone number is
displayed. If the number is withheld then 'Withheld' is displayed. Most
junk calls that I get now come from aboard and the display just shows
'International'.

For me that's quite useful. If I get an international call displayed on
the unit, I pick up the handset and *wait* until the other caller speaks
before making any sound.

If it is a genuine international call I will respond, if it is a
'congratulations, you have won blah..' tape i will drop, if it is
silence I will hold until they cut off (10 seconds or so off *their*
phone bill)

If you make a sound when you pick up the call, then the calling centre
routes the call to a human who you really don't want to talk to.
