Canadian Geographic - - ENGAGING WITH US -

The cof­fin tele­phone, also called the cam­era or box tele­phone, was the first com­mer­cial tele­phone built by Alexan­der Gra­ham Bell and Charles Wil­liams in in Bos­ton, just two years af­ter Bell re­ceived the patent for his rst tele­phone in­ven­tion — a rev­o­lu­tion­ary de­vice that could not only trans­mit, but re­ceive, au­di­ble words. The con tele­phone was made of wood, had a hand crank to sig­nal an op­er­a­tor that a call was to be placed and a trans­ceiver that a caller would use to both speak and lis­ten.
