Internet telephony system

This author is about an Internet telephony system, especially a network telephony system that automatically determines the quality of a network signal to transfer voice signals to the Internet or the Public Switched Telephone Network (PSTN).

The network used by traditional telephone lines is the Public Switched Telephone Network (PSTN), which transmits analog voice signals. However, with the rapid development of the Internet, the use of Internet Protocol (VoIP) is becoming more and more popular. (VoIP) is a telephone that transmits digital voice data technology over an IP network. The Internet Protocol (IP) was originally designed to deliver data packets, while Internet telephony is the immediate delivery of digital voice signals over IP networks. Voice over Internet Protocol (VoIP) voice transmission can be implemented in hardware or software. The early products were operated through a software architecture. Users need a computer to execute software and connect to the Internet. The computer needs a network card and microphone. However, the connection often only has half-duplex. Compared with the traditional telephone, the conversation process is like using a radio call instead of a real phone. The call quality is poor and the space is improved. There are still many software architectures for VoIP products that use software, which has the advantage of low cost. Organizational organizations may spend thousands or tens of thousands of long-distance telephone bills per month. If you can access Internet telephony with low fixed cost and unlimited access, the call charges can be greatly reduced.

Although the use of Internet telephony is inexpensive, there are still problems. The Internet Protocol (IP) is a protocol based on packet transmission. The public switched telephone network (PSTN) used in traditional telephones. ) is to take circuit switching. When transmitting voice data by IP, the system will first cut the data into packets and transmit it on the network. Since the characteristics of IP are best-effort and do not provide guarantee service, different packets may take different paths, resulting in packets. The order is disordered or lost in the middle, so the voice quality of the Internet phone cannot be guaranteed to a certain extent. The circuit switching technology using the Public Switched Telephone Network (PSTN) is a "circuit" that establishes a fixed path between the transmitting parties and retains the necessary bandwidth, so that the voice quality can be guaranteed.

As can be seen from the above description, both VoIP and traditional telephones using the Public Switched Telephone Network (PSTN) have their own advantages and disadvantages. How to preserve the advantages of both and improve the shortcomings of both should be urgent in the field. Solve the problem.

Based on the above statement, the main purpose of the present invention is to provide a network telephone system comprising: a mobile phone, a mobile phone dialing application (APP) and a voice server. The mobile phone dialing application (APP) is installed on the mobile phone. The voice server includes an RJ-45 network interface, a WIFI wireless network interface, the RJ-45 network interface and the WIFI wireless network interface. Connected to the local area network (LAN) and the Internet (Internet); an RJ-11 interface, a public switched telephone network (Public Switch Telephone Network/PSTN) dialing module, a digital analog conversion module, the RJ- The interface and the PSTN dialing module are used to connect to the PSTN network. The digital analog conversion module is used to convert the digital analog signal. The signal detection module is used to detect the quality of the network signal and decide to transfer the voice signal to the Internet. Internet (Internet) or Public Switched Telephone Network (PSTN); a microprocessor for processing the voice server signal; a general-purpose input and output (GPIO) interface for connecting other devices; and a power management module for managing The power of the voice server. When the user uses the created VoIP system, he can use one of the mobile phone applications (APP) to dial and connect to the authoring network via the local area network (LAN) via the WIFI module on the mobile phone. The voice server of the telephone system, the signal detection module of the voice server automatically detects the quality of the network signal call, and if the voice quality of the Internet (Internet) is good, the voice signal is transferred to the Internet. (Internet), if the public switched telephone network (PSTN) call quality is good, the voice signal is transferred to the public switched telephone network (PSTN). The VoIP system provided by this creation is quite innovative and progressive. It can not only make voice calls over the fixed-cost and unlimited access network, but also greatly reduce the cost of calls. It can also use the public switched telephone network (PSTN). The circuit switching technology enables the quality of voice calls to be guaranteed, both of which take care of each other. The use of analog line (PSTN) call quality is better and more stable, is not affected by network disconnection, is not controlled by the firewall, and is not limited by bandwidth. In addition, using the network phone system of this creation, the local call can be transferred to the mobile phone through WIFI, or the use area of 3G, 4G, LTE, WIMAX is wider, people are abroad, and the phone at home will not miss. It can also set conference mode call, one-to-many call or three-way call, which is convenient and easy to use. The local call can replace the previous international call through the network call, and the call charge is more economical. The VoIP phone system of this creation can also be used for tablets, and the tablet installation APP can receive the transferred local calls.
