Your receptionist answers when you cannot. But she does more: you can call her yourself. You key in your code, and then you are talking to the assistant who lived through your day.
You steer her while talking. Just say what you want differently: keep it shorter next time, always ask for the address, a bit more cheerful. She repeats back what she understood, and from the next call on she does it that way.
You ring the number shown in your dashboard — the same number your customers reach. She recognises your number and asks for your code.
No, for two reasons. Your own assistant exists only for calls arriving from your phone number; the system decides that before the call begins. And even then your four-digit code is still needed. Anyone ringing from another number simply gets the receptionist.
Yes. What you tell her about your preferences stays until you remove it — your dashboard shows exactly which instructions she has from you.
