call forwarding

Call forwarding is a telephony feature that allows incoming calls to be redirected from one phone number to another specified number. This service is commonly used to ensure that calls are answered even when the primary phone line is busy, unanswered, or out of reach. Call forwarding can be set up in various ways, including unconditional forwarding (all calls redirected), conditional forwarding (calls redirected only when busy, unanswered, or unreachable), and selective forwarding (calls redirected based on caller ID or time of day). It is widely used in both personal and business phone systems to enhance communication flexibility and maintain connectivity.
