| There are times when there is no substitute for being understood on the telephone. Well before 1937, the limitations of the telephone in accurately conveying speech were known. Today, despite modern digital trunking and switching technology, this remains a problem. Why? Analog loop lengths, building wiring, variable line equalization characteristics, poor handset and speakerphone designs, mixed networks, noise in conference rooms, paper shuffling, pen tapping, fan noise, and a host of other issues are still with us, even here in the digital age. |
