Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone communication system, and more particularly, to a telephone communication system in which a digital private branch exchange accommodates an extension terminal such as an office line, a facsimile or a telephone and forms a system.

[0002]

2. Description of the Related Art Generally, in a telephone communication system, a digital private branch exchange accommodates an extension terminal such as an office line, a facsimile or a telephone to constitute a system. In some cases, a private branch exchange or a host computer connected to a private branch exchange or the like has mail functions such as e-mail, fax mail, and voice mail. Also, conventionally,
A dedicated telephone such as a business phone is provided with display means such as an LCD (Liquid Crystal Display) to perform dial display, caller number / name display, and the like.

[0003] When a host computer is provided with this function, an e-mail is accessed by a personal computer via a network to transmit or receive an e-mail. As for voice mail, a voice mail function is realized by a key telephone and an exchange. For example, the following methods have been mainly used as voicemails by business phones. That is, (1) a method in which a dedicated voice mail device is mounted or connected to the inside of the business phone, and (2) an external voice mail device is connected via a communication path interface of the business phone, and a push button (PB) signal is transmitted. And the like. And
In order to check the recording status, the voice mail device was called from the telephone to check the recording status by voice, or the presence or absence of an e-mail was confirmed by displaying the lamp on the telephone.

[0004] Further, with respect to a fax, when a fax is received by a business phone or the like, it is common to connect a fax machine as a terminal of a main device accommodating the business phone or to install and use the fax independently of the business phone. It was a target.

[0005]

Conventionally, when e-mail is introduced into a business office, if there is already one computer, the e-mail can be checked and viewed on a desk. If there is not one, the user would have to go to a computer on another person's desk or the like to know if an e-mail was coming. Therefore, there is an inconvenience that the user has to go to the computer several times a day to check the mail, or have to stay at the computer and check everyone's mail to contact them. Also, even if there is one computer, the mail cannot be checked when the computer is turned off. Therefore, it is necessary to always turn on the power or to turn on the power every time. If the computer is turned on at all times, it costs electricity accordingly. On the other hand, if the computer is turned on every time the mail is checked, the operation is troublesome and it takes time until the computer becomes usable. Further, when there is no one computer, it is inconvenient to go to the computer every time when sending an e-mail. In addition, when the user was unfamiliar with the keyboard operation of the computer, it took time to reply to the received mail or send a new mail.

[0006] In recent years, the spread of the Internet has made it possible to obtain information by browsing homepages and distributing news / mail. Similarly, when using the Internet, each person does not have a computer. There is the inconvenience of having to go to a computer to obtain information at a business office. Conventionally, for voice mail, the only way to check the recording status at your own desk is to call the voice mail device from the telephone and check the recording status by voice, or check the presence of mail by checking the lamp display on the telephone. Was. For this reason, it was not possible to confirm how many voice mails are included, when the mail was recorded, and from whom, without calling the voice mail device in advance. In addition, since it was not possible to easily select and listen to the recorded voicemail, it was necessary to listen to the recorded voicemail in order, which was inconvenient.

Conventionally, regarding a fax, it is difficult to know whether or not a fax has been received without going to a fax machine. Therefore, when waiting for a fax that does not arrive when it arrives, it is necessary to go to the fax machine several times to confirm, which is inconvenient. Further, it is common that one fax is usually provided with one number for each office or department, and even if it is known that the fax has arrived, it was necessary to go to the fax after all.

In general, a connection between a main unit such as a business phone and a dedicated telephone generally has a configuration such as 2B + D, and a D channel (for example,
16 kbps) and B channel (for example, 6
4 kbps). In order to display web information on the Internet on this telephone, a conventional D
Since the amount of information is small in the channel, it is difficult to display at a sufficient speed. Further, by changing the information transmission interface between the main device and the telephone, it is possible to secure a sufficient amount of information, but the compatibility with the conventional telephone becomes poor. In addition, it is possible to use a new interface while maintaining compatibility by using a conversion adapter or the like, but this greatly increases the price of the system.

In view of the above, the present invention is a telephone connected to a communication system such as a business phone, which is generally installed in a business office and often installed by one person, and is provided with additional equipment such as a computer. It is an object of the present invention to provide a telephone communication system capable of confirming various kinds of information such as e-mail, fax mail, voice mail, and the Internet web without leaving the desk.

Further, the present invention provides a method of classifying different mails and various kinds of information such as e-mail, voice mail, and fax mail as appropriate, checking them collectively in a list form on a telephone, and obtaining necessary information. An object of the present invention is to provide a telephone communication system that can be selected and printed as needed. Further, the present invention can realize both a call and a mail function with one telephone even without both a telephone and a computer. It is an object of the present invention to provide a telephone communication system capable of simultaneously realizing a plurality of services such as viewing mail.

Further, the present invention enables an e-mail to be transmitted by operating a commonly used key such as a dial key of a telephone, so that even a person unfamiliar with the key operation of a computer can easily transmit an e-mail. It is an object to provide a telephone communication system. Further, the present invention provides a telephone communication system which enables a reply to a mail easily by attaching a prepared message which can be returned from a telephone and attaching a voice recorded from the telephone to a reply mail. The purpose is to:

Further, the present invention relates to a voice mail,
Information such as "from whom", "when" and "how many" are recorded can be confirmed in a list format on a telephone such as a business phone, and the recorded voicemail can be selected and heard. It is an object to provide a telephone communication system. Further, according to the present invention, information such as "from whom", "when" and "how many" of a fax can be confirmed in a list form on a telephone, and a desired fax can be selected and printed. It is an object of the present invention to provide a telephone communication system capable of performing the following. Further, according to the present invention, when printing various mail information, for example, an appropriate printer such as near the user's seat can be designated, and the output can be easily obtained without going to a fax machine or another printer.
