Speaking of phones in the movies....
A few years ago TCM had a 1960's Sidney Poitier (sp?) movie, and I can't remember its name. Filmed in Seattle, the plot was a woman who had taken a whole bottle of sleeping pills before the days of 911 and caller ID. Sidney was a volunteer in a suicide call center who took a call from her. She was calling from a hotel room. There was a lot of shots of central office guys running around tracing the call. They barely got there in time, but the woman survived.
Any way, there was little in terms of old telephones all by themselves and a lot of central office shots, but it was kind of an interesting drama.
