A communications system is designed to allow an end-user device that is coupled to a telephone set to receive activation codes that are transmitted thereto by a switch of such communications system when the telephone set is in an on-hook position. The communications system may initiate the transmission of the activation codes to the end-user device. Alternatively, the end-user device may poll the communications system to receive the activation codes therefrom. The end-user device may invoke a communications service in real time by transmitting to the communications system activation codes stored in its memory via an SVD channel modem while another SVD channel is being used for another communication service.

Method and system for transmitting activation codes to a communication device

A communications system is designed to transmit to end-user devices involved in a call information related to communications services that are invokable in real time from the end-user devices. The transmitted information includes activation codes for invoking for a usage fee, features that may or may not be subscribed to by a caller.
