Managing call control in computer telephone interface (CTI) system

A Computer Telephone Interface (CTI) system comprising:

• a wireless terminal to generate a call control message comprising call control identification information in response to a call control command from a user, and to transmit the generated call control message;
• a computer terminal to perform call control using a CTI application program upon receipt of the call control message;
• and
• an exchange to receive the call control message from the wireless terminal and to maintain the call control message generated by the wireless terminal unchanged and to interface it to the computer terminal in response to the call control identification information being detected from the received call control message.

A method of controlling a call in a Computer Telephone Interface (CTI) system, the method comprising:

• generating, by a computer terminal, a call control message comprising call control identification information using a CTI application program in response to a call control command from a user;
• transmitting, by the computer terminal, the generated call control message to an exchange;
• maintaining, by the exchange, the call control message generated by the computer terminal unchanged and interfacing it to a wireless terminal in response to detecting the call control identification information from the received call control message;
• and
• performing, by the wireless terminal, call control in response to the interfaced call control message.
