The idea of this skip is that it appears to be a phone booth. However, if you go into the phone booth and dial a number, instead of hearing the person on the line, the phone booth will play a phone conversation from that person's (the "owner" of the phone number) life).
Any attempt to communicate with the voice on the other side of the line reveals nothing. Additionally, the person in the phone booth can only hear the voice of the person on the other line talking, but not who they are talking to. It can be used to communicate to dead people, as long as they still hold ownership of a phone number.
If someone dials a phone number that is unregistered, the phone abruptly cuts off. The phone booth itself has a by-call payment system, having the phone booth person input several coins then to pay by-the-minute (as per a usual phone booth).
The story behind the phone booth is that it is indeed West Germany, 1988. A scientist desperately tries, every day, to call his wife in West Berlin, which has been disconnected from the outside world by telephone. He receives calls with his wife's voice talking, but she doesn't seem to be able to hear him. A year later, he travels to the downing of the Berlin Wall. He attempts to find his wife, when he learns that she had died 6 years prior, in 1983. The scientist publishes a report on what happened, and that's where the Foundation step in.
What do you guys think? Too similar to SCP-467? Let me know?
Oh, fyi, I ditched the whole "The Death of Taglietti" thing. If anyone wants to pick it up, feel free.
