The goal of this film was to aid in reducing customer dialing irregularities by demonstrating the correct way to use the dial telephone. It documents the shift between operator-based connections (which were on the way out) and having to dial the phone and make the connection yourself.
The dial telephone was new at this point, although the two-letter, 5-number system was still commonplace. This film even has to explain what a ringing and busy signal sound like!
