asterisk users - Aug 2007 - Converting an audio file to a ".gsm" format

Hello all,

have anyone an idea about converting an audio file (.wav, .mp3, .au,...) to
a ".gsm" audio file to use it as a voicemail file with Asterisk.

Thanks.

The program is called SoX. If you search voip-info.org you can find a
nice guide with step-by-step instructions. I would suggest you not use
the GSM format, unless you expect a majority of your calls to be in
the GSM codec.

   'sox' should be able to do this, AFAIK.
