Installation is really straightforward - plug your phone in to trueCall, and trueCall into your phone socket!

  • All phone lines - trueCall Call Blocker works on both landline and cable phone lines from all the major networks in the UK. It works fine alongside broadband. You will need the caller-ID service from your network operator to access all of trueCall's features - this is normally free but some operators make a small charge.
  • All phones - trueCall works with a wide range of phones (corded and cordless), and it protects all the phones that are plugged into it. If you have phones plugged into multiple extension sockets we would recommend that you use a multi-handset cordless system.
