- "Dialed" has always been distingished from "operator-assisted" calls
- on telephone bills. It was in the late sixties that "dialed" calls
- carried a lower rate than "operator assisted" ones which has continued
- to this day. Back then it made sense; today it is a scam.

- Yes and no. Direct nationwide dialing was introduced in the early
- fifties but it caught on slowly. When I lived briefly in southern
- California in 1956-1958 with my family (I was, after all, a kid), DDD
- was completely unknown (we were served by GTE, or "General" as it was
- known then). When we moved to San Jose in 1958, our phone could dial
- nationwide (what a fun toy!) and that service had apparently been
- available for a couple of years.
-
- DDD did not become widely available in the US until the mid-1960's.
- After many decades of using operators to complete long distance calls,
- it is understandable that even in 1971 DDD was still a slight novelty.
- But the main thing here is the importance to the plot. The murderer
- wanted a record of a "dialed" call that would prove that the caller
- had indeed made the call from the cabin outpost.

-
- The billing records are always available to law enforcement. This is
- one reason Germany and other countries claim to have no billing
- detail: to prevent government snooping. In the plot of the movie, you
- will recall that the murderer made a followup call from a paystation
- to account for that call from the cabin to the victim's wife.
- Remember, the murderer claimed to have been the one to make the dialed
- call. The whole point was to establish that the murderer was
- supposedly a hundred miles away at the time of the crime.
-
- No records are kept of INCOMING calls to telephones. This has only
- been recently technically possible, but even so it is not done at this
- time.
