Description

Handset device for VIO IP with telephone signal input device {VoIP handset with input module of telephone signal}

The present invention relates to a handset device for a VoIP, in particular having a telephone signal input device that enables the use of a VoIP phone in a manner similar to that of a conventional telephone.

Recently, various technologies and products have been developed to enable voice over IP (VoIP) using the advantage that the Internet can be connected anywhere in the world, such as a telephone network, and the cost is very low.

Hereinafter, a form of a conventional general VoIP device is as follows.

1. Existing PC-based VoIP System

As shown in Fig. 1, a PC-based VoIP system is composed of a sound card for voice processing on a PC, a call device such as a microphone / speaker for voice input and output, and most important VoIP software. Also, since it is a phone using an IP-based network, it must be connected to an IP network using a LAN or PPP.

VoIP is a technology that enables voice communication like a conventional telephone using the Internet. If you use the Internet, even if you make a phone call to a long distance, you can use it at a low rate, such as no cost or local call. In addition, there is an advantage that can provide a variety of services by simultaneously transmitting different data during a digital call. PC software-based VoIP method is advantageous to use PC-based software to install and use VoIP system at low cost. Most of sound cards and call devices are installed in existing multimedia PCs, so they can be used as they are and various software can be developed. However, users who are unfamiliar with computer use or are familiar with existing phones will not be comfortable using the computer's software to connect the phone.

In addition to using software on a PC, there is also a method of making and using VoIP dedicated telephone hardware such as a general telephone (PSTN). Dedicated phones are easy to use because they're small and have the same user interface as regular phones. On the other hand, the hardware configuration is complicated, expensive, and additional network lines for the phone have to be installed and IP numbers must be allocated separately.

2. Call device

Call devices include a microphone / speaker as shown in FIG. 2, a handset, a headset, and the like that perform the same function.

A handset is a type of microphone and speaker that is shaped like a telephone handset to connect with a computer sound card. The handset allows users to make calls using the same interface as a regular phone, which is familiar to existing phone users and is suitable for VoIP. The headset is worn on the head, and the earset is designed to be worn over the ear, without hands, so you can do other things while talking on the phone.

While headsets are convenient for people with jobs that continue to use the phone, those who don't have the hassle of putting the device in their head every time they make a call and then taking it off when the call ends. Therefore, the handset can be used more conveniently than a headset for the general user.

However, these VoIP phones are becoming more widespread because users who are accustomed to using a conventional telephone (PSTN) feel uncomfortable with how they make calls by operating the computer's keyboard and mouse. Also, users unfamiliar with computer operation have difficulty installing or operating VoIP software.

Accordingly, the present invention has devised a VoIP handset, which is a calling device that allows users familiar with existing phones to make calls using VoIP software in the same way as existing phones and to expand the scope of VoIP technology. The handset devised in the present invention adds a device for inputting a telephone signal to an existing handset, and transmits and receives the signal through a peripheral connection port of a PC, so that VoIP software can be used with the same interface as a conventional telephone.

Hereinafter, a handset apparatus for VoIP of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 4, the microphone 21 and the speaker 22 of the existing handset are configured with an input device 23 for inputting a signal, an input signal generator 24, and a port 25 for connection with a PC. The PC is composed of a port 13 for receiving an input signal, a control software (hardware driver) 12 for making the input signal available to an application program, and a VoIP application software 11. The function of each major part of the present invention will be described in detail as follows. First, the telephone signal input device 23 is composed of buttons and switches of the same type as a general telephone. It consists of buttons for entering numbers, switches for answering and hanging up calls, and buttons for supplementary services such as redial and hold. This allows VoIP phone users to call off-hook and dial in the same way as a regular phone. Input signal generator 24 is a device that when the user operates a button or switch of the handset to produce an appropriate signal that can be transmitted to the port connected to the PC accordingly. If each button generates a different signal, it is received by the PC's hardware driver and replaced with the appropriate signal for use by the PC's applications. The connection ports 13 and 25 to the PC do not require any special hardware for connection because the signal to be transmitted from the handset is simple. Generally, the game port, serial port, infrared port, USB port etc. can be used. The same function can be provided regardless of the port type, and various configurations are possible. The PC control program (hardware driver) 12 is a hardware driver software that serves to receive and interpret signals transmitted by the handset of the present invention and deliver them for use in an application program. By providing an additional API library that can be used in software production to directly receive and process the signal of the handset, the application software can easily provide a variety of additional functions through the handset of the present invention. In addition, in order to use the handset of the present invention in the existing VoIP software, it is also possible to convert the input signal of the handset into the same signal as the keyboard input or the mouse operation and transmit it to the application program. The VoIP application software 11 is composed of software for supporting general VoIP.

The operation of the present invention configured as described above allows the signal to be first transmitted to the PC 10 when the handset 20 is switched on to execute the VoIP application software 11 or to prepare for a call. Press the next phone number and press the call button to connect the call. At any time during this process, you can turn off the switch or press the end button to have the VoIP application software 11 terminate the call.Also, additional functions such as redial, hold, call forwarding, and call forwarding can be assigned to extra buttons. VoIP software 11 can perform the appropriate operation.

The control software 12 of the PC receives the input signals, converts them into ASCII codes or appropriate signals that can be used by the PC, and transfers them to the application software using the same. Although it may be provided in the form of API for efficient use, for VoIP software made without considering the handset of the present invention, the signal received from the handset may be changed into the same signal form as a specific keyboard input or mouse operation. will be.

As described above, the present invention can provide a user who is familiar with the existing phone with the same interface as the existing phone, thereby eliminating the objection to the computer operation required to use the VoIP phone. In addition, since it uses the basic input / output port of the PC and does not use any other device except the handset, it does not require any additional devices in the PC. Therefore, it does not require an IP compared to the VoIP dedicated phone, and utilizes the resources of the existing PC as it is. It can provide the same convenience. In addition to adding an input device in the form of a telephone to the handset, if the designed input device is configured in another system, VoIP phones can be applied to various systems. In other words, if you add an input device designed for a headset, a microphone / speaker, it can be used in the same way. For example, if you install the microphone and speaker using the buttons of the current bank automation corner device, you can install the VoIP campus phone without setting up a telephone network.

In addition, the existing PC-based VoIP phone can operate only one phone at the same time because the phone software must be operated while viewing the screen of the PC. However, the handset does not require an input device such as a keyboard or a mouse, nor does it need to look at the screen for a phone call. Therefore, it is a useful invention that it is possible to install a VoIP phone in a public place such as a public phone or to install and use multiple VoIP phones on a single PC.
