Problems solved by technology

However, the caller and the receiver can customize each other's digital codes, and the length of the format is limited.
[0007] According to the above, if there is no Soft Switch, Proxy or Gatekeeper to provide the terminal Internet phone to complete the client to server system registration mode, or when the Soft Switch or Proxy server is damaged or faulty, the individual phones of the Internet phone with SIP and H.323 as the communication protocol can simply execute For the point-to-point dialing mode, it will cause the user to easily press the wrong button on the phone, which violates the normal dialing habits of telephone use and seriously affects the quality of the phone operation

Embodiment Construction

[0049] figure 1 It is a schematic diagram of a preferred embodiment of the present invention. Please refer to figure 1 , the Internet phone system 100, for the point-to-point communication of a plurality of Internet phones. Each Internet phone has an Internet phone number, and each Internet phone number includes at least an area code and an identification code. The VoIP system 100 at least includes a first zone server 102 , a second zone server 104 and an uppermost server 106 . The first zone server 102 is connected to a first Internet phone 108 and a second Internet phone 110 . The first area server 102 has a first area database to record the individual codes and corresponding IP addresses of the first VoIP phone 108 and the second VoIP phone 110, and writes the individual codes and the corresponding IP (Internet Protocol) addresses into the first IP address. A zone DNS (Domain Name Server) 118 is being set. When the first Internet phone 108 dials the individual code of ...

Abstract

A net telephone system comprises one server for first section, one DNS for first section, one server for second section, one DNS for second section and one server and DNS for top layer. When dials in first net to some number in second, the first net phone query IP address of second net phone by DNS system to build point-to-point connection between the first and second net phone. When dials in first net to some number in third, the first net phone query IP address of third net phone by DNS system to build point-to-point connection between the first and third net phone.

Description

technical field [0001] The present invention relates to a network telephone system, and in particular, to a network telephone system for automatically querying the network telephone and the corresponding IP address. Background technique [0002] In the past, Internet telephony used a self-defined communication protocol to support the point-to-point transmission of data packets by using a self-defined server, and then the receiving end decompressed the packets sent by the transmitting end, and then used the relevant coding and decoding technology to convert the signal into voice. to complete the procedure of establishing a VoIP call. [0003] In recent years, VOIP Protocol promulgated by ITUT and IETF has proposed several communication protocols, such as H.323 / MGCP / MegaCo / SIP.. etc. Different package header types are defined according to different communication protocols. [0004] According to the current RFC technical documents, the MGCP and MegaCall phones need the action...
