Fig. 2 is the software configuration schematic diagram of Traditional IP phone;
Fig. 3 is the hardware configuration schematic diagram of Traditional IP phone;
Fig. 4 is the work schematic diagram of network immediate voice communication terminal.
Embodiment
The software of existing IP phone, hardware configuration schematic diagram are shown in Fig. 2,3, operation principle of the present utility model is: IP phone and embedded system is integrated, the voice channel of setting up relative client by embedded OS and procotol, immediate communication tool software combines, by communication on telephone information.
The hardware configuration of the telephone set with network immediate voice communication terminal of the present utility model as shown in Figure 1, be connected with read only memory ROM and random access memory ram on the microprocessor, be connected with the digital to analog converter A/D of microphone and receiver and D/A, network interface card, user interface, nonvolatile storage FLASH and internal memory SDRAM and analog telephone conversation module, digital to analog converter A/D, D/A are connected with microphone and receiver, microprocessor and read only memory ROM and random access memory ram are formed kernel CORE CHIP, between be connected with digital signal processor DSP.
User interface comprises dialing keyboard, display screen and the identity Verification System of swiping the card.The identity Verification System of swiping the card is formed by the IC-card card reader and with interface circuit two parts of microprocessor.
Analog telephone conversation module comprises modem chip and analog telephone part, is responsible for being connected with PSTN by the RJ11 interface, realizes the function of plain old telephone.The input and output of analog telephone part directly link to each other with loud speaker with microphone.

The communication number that the direct calling of network immediate voice communication terminal is called, under the support of instant communication server, after the network immediate voice communication terminal of initiating is received the responding call of callee's client, set up the voice messaging passage of initiator and callee's client.On function, realized dynamic binding.By having encapsulated the user's ID card of ID users, close number and other digital information, to swipe the card online.User's ID card and phone dynamic binding can satisfy the needs that the user moves.Technically, CPU, Flash, memory are embedded IP phone, support IPv4, IPv6, and RJ45 and RJ11 (plain old telephone) interface are arranged; On plain old telephone, IP phone basis, realize the function that is connected with the network instant communication software of current popular.
The basic communication process is: the user dials access code and is connected with gateway, and gateway authenticates and authorize (passing through GK) to the user, and carries out call manager.Then, GK carries out the gateway Route Selection according to the called number of user's input that gateway is sent here, selects the opposite end gateway according to called number information, and gateway call signaling address, opposite end is returned to the gateway of making a start.H.225.0 the two ends gateway uses agreement to set up and calls out, if access success, then uses H.225.0 agreement to set up voice channel at two ends.Any one party on-hook, then end of conversation among calling party and the callee.
The course of work of network immediate voice communication terminal as shown in Figure 4, its detailed process of brief description:
The first step: network immediate voice communication terminal A sends calling by the network communication server to network immediate voice communication terminal B, promptly puts through the communication number of network immediate voice communication terminal B.Network immediate voice communication terminal judges at first whether calling party is validated user, if be validated user, shows that then its good friend's address book information is for the calling party selection.
Second step: the network communication server is searched the state of customer end B in its database, sends the communication number of calling party A, and to callee's communication number, application is set up talking path with customer end B.
The 3rd step: network immediate voice communication terminal B sets up the application result of passage to network immediate voice communication terminal A loopback: if successfully set up, then return related channel program information, change the step 4; Otherwise fail clearly in the Shen, and flow process finishes.
The 4th step: after network immediate voice communication terminal A receives the callback of network immediate voice communication terminal B, the voice channel of customer end A and customer end B is successfully set up, the network information processing and control module of network immediate voice communication terminal A, network immediate voice communication terminal B is sent instruction to the Traditional IP phone module, open audio devices separately, can carry out voice call.
The 5th step: if end of conversation, side's on-hook, corresponding end signal passes to network information processing and control module, and then Communications service is cancelled, the link interruption of customer end A and customer end B, audio devices is closed.
For the dialing instruction, if converse, instruction automatically performs end; This support of address Pageup/Page down order.
