[arm-allstar] HamVoIP scripts and non-GSM sound files

[Doug Crompton]

Patrick,

   I doubt this is ever going to happen. Each sound format has its own
pluses and minues. There is a conversion program offered to convert several
formats to Ulaw - convert_audio.sh in our distribution. This converts gsm,
signed linear, and wav to ulaw. The help screen is shown below. Format
conversion is also available at a number of online sites and even Asterisk
itself in the client has audio conversion capability. We all create sound
files in different ways just like we all program in different ways. You are
completely allowed to do whatever you want in that regard. If you don't
like the format the sound files are in they can be converted or they are
available in different formats directly from Digium or other sites for
download.

# convert_audio.sh

 Convert wav file to Asterisk/Allstar formats

   convert_audio.sh <input file.wav> [output_filename]

   Input file must be .wav, output file is input filename.ul, .gsm, or sln
   unless different second parameter filename is given.
