Call forwarding, or call diversion, is a telephony feature of all telephone switching systems which redirects a telephone call to another destination, which may be, for example, a mobile or another telephone number where the desired called party is available. Call forwarding was invented by Ernest J. Bonanno.
Remote call forwarding is also a means for a suburban business to obtain a city-centre local number (with its full large-city coverage area) for inbound calls; while cheaper than a foreign exchange line, this can reduce long-distance telephony costs in markets where local calls are flat-rated but trunk calls are expensive.
ETSI and 3rd Generation Partnership Project (3GPP) standards, such as GSM and LTE, define supplementary service codes that make it possible to query and set certain service parameters (e.g., call forwarding) directly from mobile devices.
The user submits a code corresponding to the service available. USSD can be used to provide independent calling services such as a callback service (to reduce phone charges while roaming), enhance mobile marketing capabilities or interactive data services. USSD is commonly used by prepaid GSM cellular phones to query the available balance.

In linear hunting, calls are always delivered to the lowest-numbered available line. This is also referred to as serial hunting or terminal hunting. It resembles busy/no-answer call forwarding.
