A callback is a telephone service that allows a caller to request a return call from a busy or unavailable called party. The called party's telephone rings, and the caller then hangs up. The telephone system then redials the caller's number and connects the two parties.
There are two types of callback services: on-demand and automatic. On-demand callback services require the caller to initiate the return call, while automatic callback services automatically place the return call as soon as the called party's line becomes free.
Callback services can be used to reduce the cost of long-distance calls by routing the call through a local exchange. For example, a caller in New York City could use a callback service to place a call to a party in Los Angeles. The callback service would first place a call to the New York City exchange, and then the New York City exchange would place a call to the Los Angeles exchange. The entire call would be billed as a local call in both New York City and Los Angeles.
Callback services can also be used to bypass toll-free numbers that are not accessible from certain locations. For example, a caller in a country that does not have access to toll-free numbers could use a callback service to place a call to a party in the United States. The callback service would first place a call to the United States, and then the United States would place a call to the toll-free number.
