I have some doubts regarding the best quality in IVR sounds using my openvox A400P22, can you please give us some standards with the format of the fileS? the quality is very poor...we use this command: [font="]sox infile.mp3 -r 8000 -c 1 outfile.gsm resample-ql
[/font] [font="] to convert from an MP3 44100HZ 32 bits TO a wav file...
