I'm not compatible with phones
Many years ago, between 'A' levels and starting university I had a summer job working in the office of one of the largest supermarkets in the UK. My social skills were notable by their absence. Some bright spark decided to put me on the telephone switchboard. A job I hated but I did the best I could. However, one day a call came in from some senior bod at the UK head office. He asked to speak to the store manager. I buzzed through to the manager and told him there was a call for him from XYZ. His response was "I'm not in". I flicked the switch back to the incoming caller and said "He says he's not in." After a long silence on the other end of the line there was a verbal explosion with the caller shouting that somebody or other will hear about this! Thankfully, my summer job ended a few days later. It is quite possible the store manager's job ended too. Oops.
