Description

Internet phone {Internet phone}

The present invention relates to an internet telephone that can make a telephone call through an internet network with or without a PC according to a user's choice.

As communication technology, which is rapidly developing in recent years, has been widely applied to real life, it can be used for various purposes and mutually beneficial technologies are also activated.

As part of this trend, many telephone means have been developed to enable low-cost calls over the Internet, which is made possible by innovatively lowering call costs by using packet transmission instead of conventional line transmission.

The packet transmission method is used to send and receive voice and fax data by breaking up a data chunk called a packet into a line that transmits data so that packets of completely different characteristics are sandwiched between packets of the same nature. Circuits are shared rather than occupied, and the packets can be compressed as desired, reducing the cost of circuit usage.

Such Internet telephones are classified as follows according to the method.

1) PC to PC method

It is a method of making an internet phone call between two PCs through an internet server. The first Internet phone is a form of text-type chat, which is a general PC-PC communication method, developed into voice. The voice data of the sender are compressed and converted into an Internet standard signal, and then converted into voice again by the receiver PC.

This is not very different from the existing telephone system, except that it uses a PC instead of a telephone, an Internet server instead of a telephone company, and an Internet network instead of a telephone network.

However, such a PC to PC method has a problem that the computer must be turned on all the time, the computer used must always be connected to the Internet, only PC users can make calls, and the connection method is very complicated. .

2) PC to Phone

It is a method of connecting a PC and a telephone, and accessing the Internet using a PC with a specific access program, and then transmitting data to the telephone network through an Internet telephone gateway installed in a specific region to make a call through a general telephone.

That is, the call is made from a computer, but the receiving end is received from a regular telephone, which is made possible through a gateway of a service company connected to the Internet. This PC toPhone method is easier to use than the PC to PC method, but by using a gateway, a separate fee must be paid for the exchange, and the sender must use a PC, which still causes inconvenience in use.

The present invention is to solve such a conventional problem, the object of the present invention is a Phone to Phone method that can talk to each other without a PC as a normal telephone, VoIP (Voice over) that can transmit and receive a voice signal on the Internet protocol Internet Protocol (Internet Protocol) technology to provide an Internet phone that can be called over the Internet.

Another object of the present invention is to provide an Internet telephone that allows Internet calls by connecting to a PC if necessary.

The wireless Internet phone of the present invention for achieving the above object is an Internet phone with a built-in outgoing call display function to send and receive calls over the Internet using VoIP without a PC, connection, link and operation state on the front Various lamps are displayed on the rear panel, the serial port connected to the PC serial port to use the terminal program on the back, the WAN port connected to the Internet access equipment, the LAN port connected to the PC or the switch / hub, etc. A main body consisting of a telephone port connected to an external device and a PSTN port connected to a general telephone network and automatically switched to a general telephone network in the event of a power failure or a network error; A wireless telephone composed of various buttons inherent in various functions such as a liquid crystal screen for displaying an operation state and usage information on the front surface, and a interference removal button for removing interference by changing a channel when interference occurs; And a charger for recharging the cordless phone after being fixedly mounted on the support when not in use.
