Abstract

To realize various additional service functions, which are available in a main device of a conventional button telephone system, in a voice over IP telephone. [Solving Means]

A voice over IP telephone apparatus for carrying out voice communication adapted to an Internet Protocol (IP) through Internet is made to include a transmission/additional information generating and analyzing unit 12 for generating, at a transmitting side, additional information of service content to be added to transmission information related to a transmitter and a receiver as a destination, and for analyzing, at a receiving side, the additional information added to the transmission information transmitted by the transmitter to obtain the service content. The transmission/additional information generating and analyzing unit 12 is configured to check a response type for receiving, check a specified receiving communication type, and, when transmitting, generate transmission information specifying a response type at a receiving end and a communication type.

Claims

1. A method for a voice over IP telephone including a voice over IP telephone process for carrying out voice communication adapted to an Internet Protocol through Internet,

characterized in that the voice over IP telephone process comprises a transmission/additional information generating and analyzing process for generating, at a transmitting side, additional information of service content to be added to transmission information related to a transmitter and a receiver as a destination, and for analyzing, at a receiving side, the additional information added to the transmission information transmitted by the transmitter to obtain the service content.

2. The method for a voice over IP telephone according to claim 1,

characterized in that the transmission/additional information generating and analyzing process includes:

a transmission information generating process for generating transmission information related to the transmitter and the receiver as a destination;

an additional information generating process for generating additional information so as to include a response type specifying whether the receiver as a destination is requested to answer by normal response or automatic response and a communication type specifying one of one-way communication and two-way communication and be added to the transmission information;

a transmission information analyzing process for analyzing, at the receiving side, the transmission information transmitted by the transmitter to obtain the analyzed transmission information; and

an additional information analyzing process for analyzing the response type specifying whether the receiver is requested to answer by normal response or automatic response and the communication type specifying one of one-way communication and two-way communication, which are added to the analyzed transmission information, to obtain analyzed additional information added to the analyzed transmission information.

3. The method for a voice over IP telephone according to claim 1, characterized in that a door phone function is implemented by carrying out the voice over IP telephone process.

4. The method for a voice over IP telephone according to claim 1, characterized in that a recording/reproducing function is implemented by carrying out the voice over IP telephone process in an application server which is connected to the Internet and provides a service function.

6. An apparatus for a voice over IP telephone including voice over IP telephone means for carrying out voice communication adapted to an Internet Protocol through Internet,

characterized in that the voice over IP telephone means comprises transmission/additional information generating and analyzing means for generating, at a transmitting side, additional information of service content to be added to transmission information related to a transmitter and a receiver as a destination, and for analyzing, at a receiving side, the additional information added to the transmission information transmitted by the transmitter to obtain the service content.

7. The apparatus for a voice over IP telephone according to claim 6,

characterized in that the transmission/additional information generating and analyzing means includes:

transmission information generating means for generating transmission information related to the transmitter and the receiver as a destination;

additional information generating means for generating additional information so as to include a response type specifying whether the receiver as a destination is requested to answer by normal response or automatic response and a communication type specifying one of one-way communication and two-way communication and be added to the transmission information;

transmission information analyzing means for, at the receiving side, analyzing the transmission information transmitted by the transmitter to obtain the analyzed transmission information; and

additional information analyzing means for analyzing the response type specifying whether the receiver is requested to answer by normal response or automatic response and the communication type specifying one of one-way communication and two-way communication, which are added to the analyzed transmission information, to obtain analyzed additional information added to the analyzed transmission information.

8. The apparatus for a voice over IP telephone according to claim 6, characterized in that a door phone function is implemented by carrying out the voice over IP telephone means.

9. The apparatus for a voice over IP telephone according to claim 6, characterized in that a recording/reproducing function is implemented by carrying out the voice over IP telephone means in an application server which is connected to the Internet and provides a service function.
