Call forwarding sends calls that come to one number on to another, a mobile, a colleague, or an answering service, so calls get picked up even when the primary phone is unavailable.
Rules can forward calls by time of day, busy status, or no-answer, which is how businesses cover after-hours and overflow without missing callers.
Instead of forwarding to voicemail, Frontdesk forwards to an AI receptionist that actually answers, qualifies, and books the caller.
