Embodiment Construction

[0037] Such as figure 2 As shown, the telephone interface module uses the common standard telephone plug RJ11 to receive external telephones (including digital telephones and analog telephones) in a high-impedance parallel mode, that is, the recording system is paralleled directly on the telephone line that needs to be recorded. Connected to the line.

[0038] Digital telephone 5 is connected with digital telephone recording module 3, and analog telephone 6 is connected with analog telephone recording module 4. Digital telephone recording module 3 and analog telephone recording module 4 send telephone signals to DSP processing system 2 for processing.

[0039] The main function of the analog telephone recording module 4 is to convert the analog signal of the analog telephone 6 into a digital signal by an analog / digital (A / D) conversion chip, and convert the converted digital telephone signal according to the data structure required by the DSP processing module 2. Send into t...

Abstract

The invention relates to a phone-call recording system, comprising a phone interface module which receives external phone calls through a standard universal telephone plug in a high-resistance parallel mode, a digital phone-call recording module which is connected with the phone interface module and is used to conduct recording treatment to the received digital calls and to send the processed call signals to a DSP processing module; an analog call recording module which is connected with the phone interface module and is used to conduct recording treatment to the received analog calls and to send the processed call signals to the DSP module, and a DSP processing module which is used to resolve the received digital call signals and the received analog call signals and to send the resolution result to an upper software to be saved. The phone-call recording system can automatically identify the models of digital call recording and analog call recording and can start up different recording modules to record as for different call recording models, and the recording models are free from interference.

Description

technical field [0001] The invention relates to a telephone recording system, more specifically, to a telephone recording system capable of supporting digital-analog mixed insertion and its implementation method. Background technique [0002] With the rapid development of modern information technology, people's requirements for communication are getting higher and higher, and digital phones will inevitably replace analog phones as mainstream products. Compared with analog phones, digital phones have the advantages of good quality, high call clarity, high signal-to-noise ratio, and unlimited transmission distance. However, due to historical reasons, it is still a situation where analog phones and digital phones coexist. [0003] Such as figure 1 As shown, the telephone recording system in the prior art can only provide simple digital telephone recording or analog telephone recording, but in practical applications, due to the coexistence of analog telephone and digital telep...
