ABSTRACT:
A telephone time recording system is provided in which the opening part only of the voice communication that takes place during a telephone conversation is recorded, along with, amongst others, information relating to the total time of the call. The latter information may be generated as a synthesized speech and as such recorded on the same record medium as the opening part of the voice communication. The information recorded in this manner can later be used to identify the parties who participated in the call and the matter in question, and this can then be correlated with the information relating to the total time of the call, for billing purposes.
