Embodiment 1

[0026] This embodiment presents the first implementation of the present invention. The design idea is to implement part of the functions of the IP telephone system in the computer by the IP telephone, so that the IP telephone and the computer are organically combined. The program is like figure 1 As shown, the IP telephone 10 of the present invention includes a transmission and handset unit 11, a dial processing and pick-up and hook unit 12, and a dial plate 13, which are basically similar to ordinary telephones. The transmission and handset unit 11 is an analog circuit, which mainly plays a voice Signal amplification is an analog voice signal sent from the computer, which pushes the earpiece to sound after being amplified, and the audio signal of the microphone is also amplified and sent to the computer. The off-hook and on-hook part is related to the ringing circuit. When on-hook, the computer audio output signal is connected to the ringing buzzer, and once off-hook, it will be...

Embodiment approach

[0038] figure 2 The second embodiment of the present invention is shown. The difference from Embodiment 1 is that an IP phone adapter card 23 is configured in the computer, and its structure is as image 3 As shown, the adapter card contains audio filtering, amplifying unit 231, analog-to-digital / digital-to-analog conversion unit 232, data compression / decompression unit 233, RS232 level processing unit 234, serial port disconnect processing unit 235, and serial port information buffer unit 236 , And the card is also provided with an IP telephone interface 237 for connecting an IP phone and a computer interface 238 for connecting to a computer. The above-mentioned units adopt mature technologies in the field. Among them, the audio filtering and amplifying units are connected to the analog-to-digital / digital-analog conversion unit and the IP telephone interface; the RS232 level processing unit is connected to the serial port interrupt processing unit and the IP telephone interface...

Abstract

An IP telephone is composed of microphone-earphone unit, the dialing, offhock and hook-up unit and dial, and features its RS232 interface processing unit, which along with the microphone-earphone unit can be connected to computer via control and audio lines. In can send different control signals to computer according particular communication protocol and the computer can process adio and video data and compress data. It can greatly reduce the talking fee.

Description

Technical field [0001] The invention relates to a network communication device, in particular to an IP telephone used for network communication in combination with the Internet. Background technique [0002] With the continuous development of Internet technology, communication bandwidth is increasing exponentially, and the bottlenecks restricting online audio and video technologies are gradually disappearing. With the advent of the era of broadband people, IP phones will surely replace traditional telephone services and online video. The prospects of the telephone will be broader. [0003] The current domestic IP phone business is still in its infancy, so there are inevitably some problems. The IP phones that have been put into use use IP phone cards on ordinary phones to communicate with the computer network of the telephone company through a series of dial-ups. Although it can reduce call charges, it is extremely inconvenient to use. When using this kind of IP phone, you must f...
