    I found this.

    "Create a pulse code modulation (PCM) file of the desired ring
    types and store the PCM files in the root directory of your TFTP server.
    PCM files must contain no header information and comply with the
    following format guidelines:

    8000 Hz sampling rate
    8 bits per sample
    ulaw compression
    240 - 16080 samples long ( 0.03 sec - 2.01 sec )

    For example, to use sox to generate the tones, use


    sox -t wav in.wav -t raw -r 8000 -U -b -c 1 out.raw resample -ql "

    Is that saying that it a wav file? Or would be it midi file or is PCM the format? I know nothing about cisco I'm trying to help someone else.

    PCM would be the format
    the command line is using a linux tool called sox to convert a wav file into the appropriate raw file (of PCM data at 8000hz etc etc)
