Call Forwarding

Category: Tools.

Definition: A telephone feature that routes inbound calls to a different number — typically used to forward business calls to a mobile, an answering service, or an AI receptionist.

Call forwarding is a basic telephone feature that automatically redirects inbound calls from one phone number to another. It's the underlying mechanism that allows a business to use any answering service (live or AI) without changing its publicly-listed phone number.

Common call-forwarding configurations:

Unconditional forwarding. All calls forward to the secondary number immediately. Used when a business wants its AI receptionist or live answering service to handle 100% of calls.

Conditional forwarding (busy/no-answer). Calls forward only when the primary number is busy or doesn't answer within X rings. Used to keep calls on the primary line during business hours, with overflow going to a secondary service.

Time-based forwarding. Calls forward based on time of day or day of week. Used to forward only after-hours calls to a 24/7 service while keeping business hours calls on the primary line.

Selective forwarding. Calls from specific numbers are forwarded; others stay on the primary line. Less common in service businesses; more typical for executive screening.

Most modern AI receptionist services use unconditional forwarding because their pickup time and intake quality are better than typical in-house front-desk performance. Hybrid setups using conditional or time-based forwarding remain common during transition periods.

Call forwarding setup is typically a 5-minute change in the business's phone provider settings (Verizon, AT&T, RingCentral, Vonage, etc.) and requires no number porting.
