Problems solved by technology
At present, general-purpose VOIP products can only handle real-time audio streams, and the audio streams will not be saved on the terminal equipment, nor do they support playback or play the recorded voice function by the VOIP terminal products. Therefore, the VOIP terminal products of the prior art The scope of application is very limited, which is not conducive to its further promotion and application

Embodiment Construction
[0031] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.
[0032] see figure 1 As shown, it is a schematic flow chart of the method for realizing audio signal recording on the VOIP-based EPON gateway terminal device of the present invention.
[0033] In one embodiment, the method for realizing audio signal recording on the EPON gateway terminal equipment based on VOIP includes the following steps:
[0034] (1) The EPON gateway terminal equipment receives an external audio source signal;
[0035] (2) described EPON gateway terminal equipment judges whether described external audio source signal is the real-time transport protocol packet format signal, if so, then enter step (4), if not, then enter step (3);
[0036] (3) described EPON gateway terminal equipment converts described external audio source signal into real-time transport protocol packet format signal;
[0037] (4) The EPON gateway termi...

The present invention relates to a method for realizing audio signal recording on EPON gateway terminal equipment based on a VOIP. According to the method, an external audio source signal in a non RTP protocol is converted into a signal with an RTP protocol format, an audio stream file is generated according to an RTP load and is stored, and recording is realized. The invention also provides a method for realizing audio signal playing on the EPON gateway terminal equipment based on the VOIP. According to the above method, through decoding the audio stream file, playing of the audio signal is carried out by utilizing a DSP. By utilizing the methods for recording and playing the audio signal, storing conversation content and restoring a sound effect are realized, playing an audio file which is introduced from outside also can be realized, an application mode of a VOIP terminal is expanded, and the methods for recording and playing the audio signal on the EPON gateway terminal equipment based on the VOIP have the advantages of simple and convenient and application mode, low realization cost, and extremely wide application scope.
Description
technical field [0001] The invention relates to the technical field of voice telephony, in particular to the technical field of application of EPON gateway terminal equipment based on VOIP, and specifically refers to a method for realizing audio signal recording and playing on the EPON gateway terminal equipment. Background technique [0002] VOIP (Voice over Internet Protocol) terminal products are terminal products that use IP technology to implement voice calls, and generally include DSP (digit signal process, digital signal processor) and SLIC (Subscriber Line Interface Controller, subscriber line interface circuit), or modules with equivalent functionality. Through DSP to code and decode, SLIC converts the analog signal of the sound to the digital signal and converts each other to realize the voice call of IP. At present, general-purpose VOIP products can only handle real-time audio streams, and the audio streams will not be saved on the terminal equipment, nor do they...
