Cl ient) was an invention of a network data device. [Prior art]

Communication between phones. According to the advancement of network technology, many new technologies have emerged, such as Internet telephone (Vo: c = over internet Pr〇t〇c〇1, the following Jane νοιρ) technology, which refers to Voice communication on the LAN or Internet ip network can save a lot of telephone call costs, including the use of telephone communication between two Internet computers (PC t0 PC), use on Internet computers through integrated network Communication between a PBX and a general telephone (pc t〇Phone), using two telephones for the digitized conversion communication of the network through the VoIP gateway of the Internet telephone company (ph〇ne7 〇 Or use the regular note in both of them. © strike (TD nu _, _

This way back to the Internet of both sexes, V ο IP's husband; Fu / July 4 deniers & * · · · The packet is converted back to voice K, and finally sent to a phone that can be connected to the world, The analog signal of the remote route reduced to the data envelope i User '^ nj jhr 1 Shang Wener Zhu tian 4m m 1239757 V. Description of the invention (2)' ---- Ground, so that users do not need to Through the traditional public telephone network (psTN line for long-distance telephone communication. However, the existing V ο IP technology is 323 / Η248 by the International Telecommunications Union (ITU), etc. The LAN is not designed to be used in the open environment of the Internet. It has a complicated architecture and many technical restrictions on the application. Therefore, the conversion process with the public telephone network (pSTN) is more complicated, so * IETF (Internet EngineeFing Task

Force) has developed a new protocol: the Session Initiation Protocol (hereinafter referred to as 31?), Which focuses entirely on new technologies for the integration of the Internet and the public telephone network. Suan SIP belongs to the application layer protocol in the seven-layer architecture of 〇SI (〇pen System Interface), like the Cl inet-

Server architecture, and in packet processing, the packet data available in HTTp can be used to transmit instructions and status in plain text, so this sp is very suitable for the transmission architecture of a wide area network. In this sip architecture, in addition to the client-side proxy software or device (User Agent, UA), at least one host (CaU Server) needs to be established, which can be used as a proxy server (pr0xy server) and a routing server ( Redirect Server), Registry Server, Voice Mail Server, etc., are mainly formed by combining server or software with functions, which can be combined with the existing public telephone network (PSTN), VoIP and other related services.

The network data device i of the present invention is provided with at least one near port 11, one remote connection 2 and at least one Internet telephone port 13, and an internal processing module is provided in the network data device i. Group 丨 4 and a voice processing module 15, wherein the near-end port 丨 丨 can be coupled to the near-end device 2 or the internal local area network 31 via a transmission line (such as an Ethernet cable), and the remote The end port 12 can be coupled to the Internet 32, and the Internet phone connection 槔 13 is used to couple at least one Internet phone (ppone). > The SIP processing module 14 is electrically connected to the near-end port n and the far-end port 12 and can control the data packet signal transmission with the near-end device 2 through the near-end port n. Or control the data packet signal transmission with the Internet 32 via the remote port 2. The voice processing module 丨 5 is electrically connected to the Internet phone port 1.3 and the S IP processing module 14 to convert the voice signal generated by the Internet phone into a data signal and send it to the SIP. The processing module 14 converts the data signal sent by the sip processing module 14 into a voice signal and transmits it to the network electrical activity. Therefore, the user can directly use the Internet phone to communicate with the remote voice. ^ Secondly, the circuit of the S_IP processing module 14 is mainly composed of a micro processing unit 141, two memory units 142, and a plurality of transmission units. The micro processing unit 141 is mainly responsible for executing the SIP servo program and the memory. The unit 142 is electrically connected to the micro processing unit 141. There are two types of memory (ROM) that can be used to store the servo program to be executed. The random access record is only on page 10 1239757 V.
