In the past, cellular network operators earned revenue based off minutes sold. That's why voicemail has very verbose instructions that are read to you every single time. It's a way of inflating average call duration and thus revenue.
These days with unmetered calling, the receiving telco still makes some money off incoming calls through termination charges.
