Call forwarding is a telecommunications feature that redirects incoming calls from one phone line to another. This process allows individuals to receive calls intended for their primary phone number on a different device or phone line. For example, a call directed to a home phone can be seamlessly rerouted to a mobile phone or an office line.
The value of this functionality lies in its convenience and accessibility. It ensures that important calls are not missed, regardless of location or availability at the primary number. Historically, this was a key feature for businesses and individuals who needed to remain reachable while away from their main telephone. It provided a level of flexibility that predates widespread mobile phone usage.
