Red Interdimensional Telephone

The Red Interdimensional Telephone, or R.I.T., was a device purchased at cost by the Man in Grey when he set up the Multidimensional Finders Service. On it, Jenny Over-There was able to receive calls from anyone in the Multiverse. The Man in Grey was able to choose the phone number himself; it was a relatively rare one, but phone calls meant for unrelated people in the Multiverse who shared the number still somehow ended up contacting the R.I.T. instead.
