The square dance last used FTP or TFTP to the PCM package downloaded from the router,PCM capture tool can only be used in analog voice port FXO and port FXS. B, Huawei R Series Router Enter the super user view [huawei]super Input password here [huawei-supervisor] Use the h-dsp PCM [channelNo] command can grab a 1 minute PCM data, the capture process, if the repeated execution of h-dsp PCM [channelNo] command, will see the size of the growing, grasps will prompt (the red part of the text), eventually capture PCM data filesize is about 964K, if the file size is too large, then grab bag has a problem, please re crawl. 192.168.1.1 as an example to demonstrate the following: [huawei-supervisor] [huawei-supervisor]h-dsp PCM 0 Channel 0 start capture PCM data packet, addr:0x7cb34b4 [huawei-supervisor]h-dsp PCM 0 Channel 0 has been capturing PCM data packet, size:40488, addr:0x7cb34b4 Please h-dsp PCM free first.
