The term call supervision is used to describe a process completed by a sophisticated telecommunications switch.

The switch will "supervise" the call by determining if the call has been answered. If the call is not answered (sometimes within a specificed number of 'rings'), then some other predetermined action is ordered. In a residential application, the call may go to voice mail. In a business application, the call might be directed to a call answering center. Supervision is a network function, not to be confused with 'call forwarding'. The local telephone company 'Call Forwarding' offering may only allow for a single line to be re-directed elsewhere. Supervision allowing 'call overflow' can only be performed by a facility which subscribes to large line capacity and possesses adequate technical capability. If purchsed from a local carrier, EACH additional outbound call path must be specifically ordered and has a line limit.

	Most organizations recieve their toll free calls over local lines. Their ability to receive simultaneouse calls is limited to the number of local lines installed. Some organizations purchase alternate routing from the local phone company. (This includes "call forwarding".) Again, the number of simultaneous calls going to the alternate destination is limited to the number of lines, often less - as in the case of call forwarding only a single line can be used at a time. The purchase of multi-line alternate routing is available from the long distance provider at an extra fee. This requires an additonal monthly fee, AND a higher usage fee for all calls. Finally, the addition of "supervision" for virtually unlimited simultaneous line use is available from Telecompute, often at low or no additonal cost.

Supervision may be purchased from a long distance carrier or toll free (800) provider. This method, similar to that provided by Telecompute, provides for virtually unlimited call "overflow".
