Abstract
A computer telephony interface adapter (CTIA) for interfacing a computing device, a telephone, and a telephone network. The CTIA communicates with the telephone network using a telephone network protocol, such as a PSTN or a PBX protocol. Also, the CTIA communicates with a POTS telephone or a PBX telephone according to the telephone network protocol and with the computing device according to a data communication protocol, such as a USB or wireless protocol. The CTIA includes a controller in communication with the telephone network, the telephone, and the computing device. The controller converts communications between the telephone network protocol and the data communication protocol. In addition, the controller selectively couples the telephone into communication with the telephone network and the computing device at the same time. Thus, the CTIA enables local control over real-time shared communication among the telephone, telephone network, and computing device.
