Three things get called "answering" that aren't the same product. Voicemail records a message most callers won't leave. An IVR ("press 1 for…") routes button-pushes and books nothing. A human answering service takes a message for $3–4 a call and texts it to you to deal with later. An AI receptionist is a fourth thing: software that holds an actual conversation — understands what the caller needs, asks the follow-ups you'd ask, and takes an action on the spot.
The action is the point. A receptionist that can only say "I'll pass that on" is voicemail with better manners. Giday's receptionist books the job into a live calendar during the call, sends the SMS confirmation before the caller hangs up, quotes real prices where you've approved a price list, and screens the telemarketers out for free instead of turning them into "messages" you pay to read.
