3 Stop recording (to internal RAM)
4 Store data from internal RAM to flash file system.
Using the same <audioFilePath> name again will overwrite existing file.
Storing from RAM to FFS can only be done after stopping recording. Otherwise
command will return error.
Audio file path
Parameter is mandatory if <audioFileCmd>=0 (Start playback) or <audioFileCmd>=2 (Start recording).
Please consider that there is only one buffer in RAM available for voice prompts. The RAM may contain either
a voice prompt loaded from the FFS or a recorded voice prompt. Therefore, loading a file from the FFS will delete
a previously recorded voice prompt. Vice versa, recording a voiceprompt first clears the RAM.
The maximum length of the path and file name string is 127 characters.
The maximum size of each AMR file is 64 kBytes including 6 Bytes for the file header.
To select a voice prompt for playback from the FFS the *amr.file must be given as a fully qualified path and file
name (beginning with "a:". Directory separator is ''/'' (002Fh). Example: a:/PATH/TO/VOICEPROMPT/file.amr
To play the voice prompt currently held in the RAM (file loaded from FFS or recorded via AT^SAFH=2), simply
enter quotation marks "".
