What is another word for trunk call?
Pronunciation: [tɹˈʌŋk kˈɔːl] (IPA) 
Trunk call is a dated term that refers to a long distance telephone call made through a network of switchboards or trunks. Modern technology has made trunk calls a thing of the past, and the term has largely fallen out of use. Synonyms for trunk call include long-distance call, international call, intercity call, and operator-assisted call. Nowadays, people can easily make long-distance calls through mobile phones, VoIP, and other digital communication platforms at lower costs and faster speeds. As such, it's unlikely that the term trunk call will make a comeback.
