When a collect call is initiated by a calling party, and the call is routed to an operator services position, an automated attendant, or other system in the telephone network. In addition to playing an announcement to the called party to determine if he or she will accept the call, information is furnished to the called party, preferably by an announcement, indicating (a) the anticipated cost for the call, and, optionally, (b) the relative cost of the call, as compared to the cost that would be imposed if another carrier carried the call. This information may be obtained using the dialed number and information identifying the calling party location, and by querying a database containing (a) rate information, and optionally (b) comparative information setting forth the rates of different carriers offering collect call service in the same calling area. The invention can be practiced in an automated attendant, sometimes referred to as an interactive telecommunications services platform, which may be part of (a) a switch in a local exchange network, or (b) a switch in an interexchange (long distance) network. The collect calls may be originated by dialing a 0+call, or by calling a predetermined 800 number such as 1-800-CALL ATT.
