An
operator-assisted call is one in which the
calling party places a
telephone call which requires an
operator to provide some form of assistance in completing the call. This may include
telephone calls made from
pay phones, calls placed station-to-station, person-to-person,
collect,
third number calls, calls billed to a
credit card, and certain
international calls which cannot be dialed directly. The telephone operator may also be able to assist with determining what kind of technical difficulties are occurring on a phone line, to verify whether a line is busy (Busy Line Verification, or BLV), or left off the hook, and break in on a phone line to request for the caller to clear the line for an incoming call (Busy Line Interruption, or BLI). The latter service is often utilized by emergency police. In addition, operators are often a first point of contact for the elderly wanting information on the current date and time.
