Communication control unit

Abstract

An extension telephone using an ordinary telephone circuit cannot be coordinated with a data terminal connected by an IP network. An extension telephone using an ordinary telephone circuit has none of the convenient functions of an IP telephone, such as implementing outgoing/incoming call data management and telephone book management on a PC. A telephone terminal using an ordinary telephone circuit and a data terminal in an IP network can however be coordinated by reflecting telephone calls and call signal details in an IP network by means of a telephone adapter which can send and receive IP network data and call signals using IP network data as a trigger. A user of an ordinary telephone system can easily coordinate a telephone with a data terminal, and even if there is a “modernization time lag” between the data system and telephone system, or the IP telephone system is introduced gradually, an environment is created whereby all users can make maximum use of coordination between the data system and telephone system.

Claims

1. A communication controller connected with a telephone terminal and a communication control unit, said controller comprising: a receiving unit which receives communication data between said telephone terminal and said communication control unit; anda control unit which analyzes this communication data, acquires the status of said telephone terminal, and notifies this status to another communication device.

2. The communication controller according to claim 1, wherein, instead of analyzing said communication data, the status of said telephone terminal is acquired by detecting at least one physical operation among the raising or lowering of the receiver of said telephone terminal, or the depression of a button.

3. The communication controller according to claim 1, wherein said other device is a data terminal, and said notification is performed via a signal line which connects said data terminal and this communication control unit.

4. The communication controller according to claim 1, wherein said other communication device is a server, and said notification is performed via a signal line which connects said server and this communication control unit.

5. The communication controller according to claim 1, wherein the status of said telephone terminal is the communication status of this telephone terminal.

6. The communication controller according to claim 1, wherein the status of said telephone terminal is an up/down status of a hook of this telephone terminal.

7. The communication controller according to claim 1, wherein the status of said telephone terminal is at least one of the status of the outgoing call from this telephone terminal, outgoing call destination data, outgoing call source data, status of incoming calls to this telephone terminal, incoming call destination data and incoming call source data.

8. The communication controller according to claim 1, wherein the status of said telephone terminal is a setting performed by this telephone terminal in said communication control unit.

9. The communication controller according to claim 1, wherein the status of said telephone terminal is a busy response to an outgoing call of this telephone terminal.

10. A communication controller connected to a telephone terminal, comprising: a receiving unit which receives a signal from a device other than this telephone terminal; anda control unit which sends a call signal based on this signal.

11. The communication controller according to claim 10, wherein the device other than said telephone terminal is a data terminal connected to this communication control unit by a signal line.

12. The communication controller according to claim 11, wherein the device other than said telephone terminal is a server connected to this communication control unit by a network signal line.

13. The communication controller according to claim 12, wherein the controller determines an appropriate action based on a signal received from said server prior to sending said call signal.

14. The communication controller according to claim 10, wherein the destination of said call signal is a communication control unit.

15. The communication controller according to claim 10, wherein the destination of said call signal is said telephone terminal.

16. The communication controller according to claim 10, wherein the destination of said call signal is both said telephone terminal and said communication control unit.

17. The communication controller according to claim 10, wherein the signal from a device other than said telephone terminal is a telephone setting request to said communication control unit.

18. The communication controller according to claim 10, wherein the signal from a device other than said telephone terminal is presence data transmitted from a server.
