Question

why always in call Always we say first hello​

Answer 1

Answer:

The dictionary says it was Thomas Edison who put hello into common usage. He urged the people who used his phone to say "hello" when answering. His rival, Alexander Graham Bell, thought the better word was "a- hoy-hoy.” The receiving call is always confirmed by saying Hello.Immediately introduce yourself. Upon picking up the phone, you should confirm with the person whom they have called. In personal calls, it's sufficient to begin with a "Hello?" and let the caller introduce themselves first.
