专利汇可以提供Automatic answering telephone system专利检索,专利查询,专利分析的服务。并且PURPOSE: To avoid erroneous recognition of termination of a phone call by an opposite party or making of a phone call to other party regardless of a still connected line by providing an audible tone generating means generating an audible tone for a prescribed period when a subscriber line is acquired in the home stay mode.
CONSTITUTION: When an incoming tone is detected for a prescribed number of times in the home stay mode, a subscriber line 7 is acquired for a prescribed period and an audible tone generating means 10 generates an audible tone for the prescribed period. Thus, the user at home listens to the audible tone to recognize that the subscriber line is being acquired. Thus, the erroneous recognition of termination of a phone call regardless of a still connected line or an event of making a phone call to other party is avoided.
