Abstract: Call control messages and audio signals between a telephone device and a computer network telephone client on a computing device can be intercepted. For control messages from the computer network telephone client, the control messages can be translated from a first control protocol to a second control protocol and forwarded to the telephone device. For control messages from the telephone device, the control messages can be translated from the second control protocol to the first control protocol and forwarded to the computer network telephone client. For audio signals from the computer network telephone client, the audio signals can be translated from a first audio protocol to a second audio protocol and forwarded to the telephone device. For audio signals from the telephone device, the audio signals can be translated from the second audio protocol to the first audio protocol and forwarded to the computer network telephone client.

Abstract: A method for transferring a telephone call includes receiving a communication at a first client computer from a second client computer. The first client computer and the second client computer run communication software that supports voice over Internet Protocol. The communication includes a request to transfer the telephone call to the first client computer. After receiving the communication from the second client computer at the first client computer, determining whether to accept the telephone call. When a determination is made to accept the telephone call, an action is initiated at the first client computer that causes the telephone call to be transferred to the first client computer.
