Forgive me for posting Radio 4, but this could be a lightly interesting documentary about the uncanniness of the telephone. On tonight (14/12/13) at 8pm... contains Chuck Palahniuk
Reminds me of Long Distance Call, a great Twilight Zone episode where a young boy talks to his recently deceased grandmother on the telephone. For most of the episode his parents, as ever, try to talk him out of his illogical conviction and blame his imagination and grief for the problem. Nevertheless, the boy swears he can talk to grandma. At the end of the episode his mother snatches the telephone from him and, upon putting it to her ear, exclaims "It is her, I recognise her breathing!" Great episode, can't find it online but you can probably torrent it.
