Telephone sound-recording system and implementing method thereof

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...

However, due to historical reasons, it is still a situation where analog phones and digital phones coexist

[0003] like figure 1 As shown, the telephone recording system of the prior art can only provide pure digital telephone recording or analog telephone recording, but in practical applications, due to the coexistence of analog telephone and digital telephone, it is necessary to record these two telephones simultaneously , but the telephone recording system in the prior art is difficult to take into account both the number and the analog telephone, and cannot well adapt to the application requirements of different users
