Who'd have a landline? Thanks to cunning new call-centre tactics, millions of us have to put up with automated messages, silent calls or someone trying to sell us a new gas supply. But you can avoid this irritating phone-spam with a device called the trueCall. Simply plug your phone into this little gizmo and you can create a friends and family user list of callers. The idea is, if a random number appears, the trueCall intercepts it, and lets you know who is calling without putting them through. www.truecall.co.uk ; 0800 0336 339
