BT Caller ID compatable modem

[Jamie Bennett <jamie.bennett@xxxxxxxxx>]

Hi,

I'm putting together a cheap media center pc for my parents who have
suddenly decided to get all technological on me. They really want
caller id on there but I'm at a loss to see what modems that are
currently available support the BT standard. I've read the uk caller
id FAQ but that seems to mention modems that are either not in stock
anywhere or have been discontinued. Can anyone point me in the right
direction to the cheapest possible (only want the caller id bit as
they are on broadband) modem that is available now?

Thanks,

Jamie
