For those of you out there who forgot or never learned.
If you’re the caller:
“Hello, this is <your name here> with <place of business/organization>. May I please speak with <Mr./Ms. Lastname>?”
If you are answering the phone at a place of business:
“Hello, <business name>. (optional: This is <your name>.) How may I help you?”
If you are at your house: “Hello?” Note, it is up to the CALLER to identify him or herself and have some idea who is at the number being called.
Just a little PSA for those of you who need a refresher! ;-)
