Abstract

PURPOSE: An in-plant wired/wireless consent call method is provided to easily forward a call and consent only with an extension number between an extension phone user and a wireless subscriber by providing a consent function for a call in a busy state to the wireless subscriber through a private exchange rather than passing through a PSTN when the wireless subscriber is registered as an in-plant subscriber. CONSTITUTION: It is checked whether the first and second wireless subscribers are in a call communication. It is checked whether there is an input of a 'SEND' key from the first wireless subscriber. If there is an input of the 'SEND' key from the first wireless subscriber, a hold message is transferred to the second wireless subscriber to make the second wireless subscriber be in a call hold state. When the second wireless subscriber is in a hold state by the input of the 'SEND' key, the third subscriber is called and a speech path is formed for a consent call communication. After the third subscriber makes the consent call communication, when the first wireless subscriber intends to perform a call communication with the second wireless subscriber, the first wireless subscriber makes the third wireless subscriber to hear a hold sound by input of the 'SEND' key to hold it, and depresses the 'SEND' key two times to cut off the hold sound of the second wireless subscriber to resume a call communication.
