Description of the Related Art Conventionally, as a method of detecting a partner response in a communication device terminal, a method of detecting polarity reversal of a telephone line due to an operation of an exchange has been used. However, this method is effective when directly connecting a communication device terminal to a telephone line, but is effective when connecting to an extension of a collective office telephone or private branch exchange telephone, or to an extension of a single telephone accommodation facility such as a business telephone. Since the inversion of the telephone line cannot be detected, it is not possible to detect the callee's response, and it may not be possible to calculate a call charge, transfer a message from an answering machine, or the like.
