I am over 50 years old. My Mom was a Bell Telephone operator. If I learned nothing else at her knee, I learned telephone manners. "Who is this?", either from the caller or the person called, is the ultimate rudeness to me. I can't say that I always identify myself when I am making a personal call or appointment, but, this is the usual way: "Hi ____(if I know them), this is Dale-Ann, is So and So available?" If I need to take a message: "May I tell ____ who called? Or if I am screening the calls "May I ask who is calling?" If I am making a business call, I do always identify myself and company. "Hello. This is Dale-Ann from such and such. Is so and so available?"
Dale-Ann
Dale-Ann
