[0002]
[Prior art]
In recent years, a VoIP (Voice Over Internet Protocol) telephone has been commercialized which converts voice data into packet data and transmits the packet data over an IP (Internet Protocol) network, thereby enabling a telephone call using the IP network. ing.
[0003]
As a call control protocol of the VoIP telephone, H.264 standard of International Telecommunication Union- Telecommunication Sector (ITU-T) standard is used. H.323, and SIP (SeSession Initiation Protocol) standardized by IETF (Internet Engineering TaSK Force).
[0004]
H. In H.323, the data is in a binary format, and in the SIP, the data is in a text format. Also, when data is transmitted, H.264 is used. In H.323, data is encoded and converted into a bit string, and then transmitted as an IP packet. In contrast, in SIP, data can be transmitted as text data as an IP packet.
[0005]
Many proposals regarding such a VoIP telephone have been made. For example, when a telephone number is selected on a display screen of a personal computer, the selected telephone number is transferred from the personal computer to the VoIP telephone, and a call is made to the telephone number destination transferred on the VoIP telephone side. (For example, see Reference 1).

[0058]
In step S13, the control unit 110 stops displaying the name data on the display unit 7 by controlling the display unit 7, stops outputting the ringtone from the speaker 9, and proceeds to step S14.
[0059]
In step S14, the control section 110 disconnects the line by controlling the IP network I / F section 3, and ends the processing.
[0060]
Next, the operation of the personal computer 170 will be described.
[0061]
FIG. 5 is a flowchart showing the operation of the personal computer 170.
[0062]
In step S20, when the control unit 20 determines that there is a telephone directory registration operation from the input unit 22, the process proceeds to step S21.
[0063]
In step S21, the control unit 20 stores the telephone number and name data input from the input unit 22 in the storage unit 21 in pairs, and proceeds to step S22.
[0064]
At this time, the user inputs the telephone number and name by using, for example, a JIS keyboard. In addition, data such as a name may be input from another personal computer or HDD.
[0065]
In step S22, when detecting a signal indicating that there is an inquiry for information (for example, name) corresponding to the telephone number from communication unit 25, control unit 20 proceeds to step S23, and otherwise proceeds to step S20. Reverse processing.
[0066]
In step S22, the control unit 20 controls the communication unit 25 so as to detect the address of the inquired device, and stores the address in the storage unit 21 temporarily or permanently.
[0067]
In step S23, the control unit 20 fetches the telephone number data received from the terminal (for example, the VoIP telephone 140) that the communication unit 25 inquired, and stores the same telephone number data as the fetched telephone number data in the storage unit 21. If it is determined that it is stored, the process proceeds to step S24; otherwise, the process proceeds to step S25.
[0068]
In step S24, the control unit 20 reads out the name data corresponding to the telephone number determined to match in step S23 from the storage unit 21 and subsequently controls the communication unit 25, thereby controlling the communication unit 25 in step S22. In this case, the read name data is transmitted to the address of the other party (here, the VoIP phone 140) stored temporarily or permanently.
[0069]
In step S25, control unit 20 causes VoIP phone 140 to transmit text data (for example, “no data”) indicating that there is no name data, and ends the processing.
[0070]
As described above, in this embodiment, when there is an incoming call to the VoIP telephone 140, the VoIP telephone 140 acquires the telephone number data of the calling side, and inquires of the name data corresponding to the acquired telephone number data. This is performed to a predetermined destination (for example, personal computer 170). The personal computer 170 that has received the inquiry transmits name data corresponding to the received telephone number to the VoIP telephone 140. When the VoIP telephone 140 receives the name data from the personal computer 170, the personal computer 170 transmits the received name data. It is displayed on the display unit 7.
[0071]
For this reason, the VoIP telephone 140 can display name data without having a large-capacity telephone directory memory, and the name data displayed on the VoIP telephone 140 is the name stored in the personal computer 170. Since the data is data, the user of the VoIP phone 140 does not need to perform a complicated character input operation using the numeric keypad.
[0072]
Further, since the name data is stored in the personal computer 170, the name data can be easily input using an input device such as a JIS keyboard.
[0073]
In this embodiment, the VoIP telephone 140 inquires of the personal computer 170 about the telephone directory data. However, for example, the VoIP telephone 140 inquires of the personal computer 170 about the telephone directory data. The server (not shown) may be configured to make an inquiry about telephone directory data.
[0074]
In this embodiment, the VoIP telephone 140 inquires the personal computer 170 of the telephone directory data via the LAN 120. However, the VoIP telephone 140 and the personal computer 170 are connected by, for example, an RS-232C cable, and the VoIP telephone 140 May directly inquire of the personal computer 170 about telephone directory data.
[0075]
With such a configuration, it is possible to obtain information from a personal computer without incurring a communication fee, and it is not necessary to put a burden on a network.
[0076]
Further, when the VoIP telephone 140 receives the name data corresponding to the telephone directory data, the data may be stored in the telephone directory memory, and the user may select whether to store the data or not.
[0077]
With such a configuration, for example, information such as a telephone number can be received from another database not owned by the user, and stored as own telephone directory data. That is, data can be easily collected and created.
[0078]
The data is not limited to name data, but may be personal data such as a nickname, address, age, blood type, date of birth, and the like.
[0079]
With such a configuration, it is possible to recognize who the other party is. For example, when there is an acquaintance with the same name, it is possible to make it easier to recognize from whom the incoming call is made by displaying a nickname or address at the time of the incoming call.
[0080]
In this embodiment, the personal computer 170 is inquired about the name data corresponding to the telephone number data. However, the personal computer 170 may be inquired about the name data corresponding to the other party's address (for example, a mail address or an IP address).
[0081]
In this embodiment, the information such as the name is displayed during the incoming call, but the information such as the name may be displayed after the off-hook of the incoming handset.
[0082]
【The invention's effect】
