Sometimes you need both hands for something else while on the phone. Landline telephones mostly had handsets that looked like the top photo here [1]. When held with a hand they were positioned as shown in the second photo there. Because of its thickness and length you only had to tilt your head and/or raise you should a little to hold it hands free with the speaker end right at the ear and the mic end still near the mouth. If you were taking a call while standing for example and needed to write something down in a notebook that was no problem.
