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 (step S42). When it is judged that the identification information is added, the wireless terminal automatically answers the call (step S43). 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 CTI system comprising a key telephone main unit accommodating an extension line and an external line and connected to a computer network, a wireless terminal used as an extension telephone set and adapted to be wirelessly connected to an antenna connected to the key telephone main unit, 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 comprising 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.

2. The CTI system as claimed in claim 1, wherein the wireless terminal comprises a sound volume control part for controlling the volume of a receiving sound when the call is automatically answered.

3. The CTI system as claimed in claim 2, wherein the sound volume control part has a motion detecting portion for detecting a motion of the wireless terminal so as to change the volume of the receiving sound when the motion of the wireless terminal is detected.

4. A 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, a wireless terminal used as an extension telephone set and adapted to be wirelessly connected to an antenna connected to the key telephone main unit, 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 answering the call in case where the call includes the code.

5. The CTI control method as claimed in claim 4, wherein the wireless terminal increases the volume of a receiving sound to a first predetermined sound volume when the call is automatically answered.

6. The CTI control method as claimed in claim 5, wherein the sound volume control part detects a motion of the wireless terminal to decrease the volume of a receiving sound to a second predetermined sound volume.

7. A wireless terminal for use in a CTI system, the wireless terminal comprising:

a judging part for judging whether or not identification information is added to a call signal, and

an automatic answering part for automatically answering a call if the judging part detects that the identification information is added to the call signal.

8. A key telephone main unit for use in a CTI system, the key telephone main unit comprising:

an identification information adding part for adding identification information to a call signal when a wireless terminal associated with a personal computer is called in response to a transmission request from the personal computer.
