Sounds to me like this guy has an anxiety disorder that he's masking as a hatred of phones.
>Recently, when I was at mum’s alone, the house phone rang. I didn’t answer it. It rang again immediately. I didn’t answer it. It rang again immediately. I stood over it, willing it to stop, palms sweating. The stand-off was only broken when mother texted me to tell me to answer the phone. I hate telephones.
