The line is answered the way a client's line is: a greeting in the business name, on a recorded line, then "How can I help you?". Verity is answering as Giday's receptionist, so she can tell you about plans and how it works, take a message, or book you a call with a human.
The call is recorded, and she says so in the greeting. That notice is inside the greeting on every Giday line and can't be switched off — by us or by a client.
