Abstract

In a CTI system, when a wireless terminal is called in response to a transmission request from a personal computer, a key telephone main unit adds to a call signal identification information indicating that a call is based on the transmission request from the personal computer. When the call is received, the wireless terminal judges whether or not the identification information is added to the call signal. When it is judged that the identification information is added, the wireless terminal automatically answers the call. Otherwise, the wireless terminal does not automatically answer. Thus, in case of transmission from a CTI application, operability and convenience are improved.

Claims

1. A Computer Telephony Integration (CTI) system comprising a key telephone main unit accommodating an extension line and an external line and connected to a computer network, an antenna connected to the key telephone main unit, a wireless terminal used as an extension telephone set and configured to be wirelessly connected to the antenna so that the key telephone main unit exchanges directly with the wireless terminal, and a computer terminal connected to the computer network and associated with the wireless terminal, the key telephone main unit calling the wireless terminal associated with the computer terminal in response to a transmission request from the computer terminal, wherein:

the key telephone main unit comprises an identification information adding part for adding, upon calling the wireless terminal in response to the transmission request from the computer terminal, to a call signal identification information indicating that a call is based on the transmission request from the computer terminal;

the wireless terminal comprises a judging part for judging whether or not the identification information is added to the call signal and an automatic answering part for automatically answering the call if the identification information is added to the call signal, said automatic answering part does not automatically answer the call if the identification information is not added to the call signal;

the wireless terminal comprises a sound volume control part for increasing a volume of a receiving sound to a first predetermined sound volume when the call is automatically answered; and

the sound volume control part comprises a motion detecting portion for detecting a motion of the wireless terminal so as to decrease the volume of the receiving sound to a second predetermined sound volume when the motion of the wireless terminal is detected.

2. A Computer Telephony Integration (CTI) control method for use in a CTI system comprising a key telephone main unit accommodating an extension line and an external line and connected to a computer network, an antenna connected to the key telephone main unit, a wireless terminal used as an extension telephone set and configured to be wirelessly connected to the antenna so that the key telephone main unit exchanges directly with the wireless terminal, and a computer terminal connected to the computer network and associated with the wireless terminal, the key telephone main unit forming a speech path between the wireless terminal associated with the computer terminal and a destination telephone set in response to a transmission request from the computer terminal, wherein:

the key telephone main unit sends, upon calling the wireless terminal in response to the transmission request from the computer terminal, a code indicating that a call is based on the transmission request from the computer terminal,

the wireless terminal automatically answers the call in case where the call includes the code, the wireless terminal does not automatically answer the call in case where the call does not include the code;

the wireless terminal increases a volume of a receiving sound to a first predetermined sound volume when the call is automatically answered; and

when the wireless terminal detects a motion of itself, the wireless terminal decreases the volume of a receiving sound to a second predetermined sound volume.
