摘要：
An exemplary telephone apparatus which can transfer a first phone call from a Bluetooth enabled cellular phone to a home phone and, making a second cellular phone call by a home phone via a Bluetooth enabled cellular phone, includes a Bluetooth enabled integrated chip (IC). The IC includes a Bluetooth modem configured for receiving a Bluetooth signal from a Bluetooth radio frequency (RF) antenna of the cellular phone, a central processing unit (CPU) built-in the IC, for switching controlling of transferring between the first phone call and the second phone call, and a digital signal processor (DSP) and a CODEC built-in the IC. The telephone apparatus makes use of digital signal processing technology to generate and decode various tones and signals. The telephone also avoids the problem of distortion of DTMF tone during transmission through a Bluetooth RF.
