I am going to step in here and offer my own take on this. The use of a phone for me is for brief businesslike communication and not for chatting. It is just the way I am. Call it what you will, maybe 'phone anxiety', but I find it excruciating to linger on a phone just talking. I call and say what needs to be said in as concise a manner as possible, often with what I need to say having been rehearsed. I leave the chit-chatting for in person. Never could I video chat either. I think my friends and family understand this. If the person is too far away to see in person, my preferred communication is email. I am just completely incapabe of gabbing on a phone.
