I'm working on my 100Th YouTube video, I will be making some 100 Year phone calls. 100 Year span of telephone technology. These will be from Magneto phones from the 1900's, phones thru 100 Year switchboard then a later 1930's model combination magneto/common battery switchboard to a late 50's 3CL toll switchboard, completing Call's to a SXS and A asterisk system T1- TDM to VOIP format to a 2020 iPhone. The video will include audio as the calls are set up. The video will start with a very quick overview then calls, and the last part will be a brief description of the technology that was used. This has not been done by anyone I'm not sure on the correct title. Any comments or suggestions would be welcomed.
Most of the calls will be using Western Electric equipment. one of my oldest phones is a Strom-berg Carlson Wall phone.
