【発明の名称】ビジートーンの事前学習方法及びビジートーンの識別方法
Document Type and Number:
Japanese Patent JP2731139
Kind Code:
B2
Abstract:
The present invention provides an automatic answering system that, upon being provided with operating power, uses a tone pattern learning operation to identify an applicable busy tone pattern. After the applicable busy tone pattern is identified, when a calling party records a message on a recording medium of the system, the system performs a detection mode subroutine corresponding to the identified busy tone pattern and detects the busy tone in a rapid and accurate manner. As a result, unnecessary use of the recording medium is eliminated.
