First off, Digium provides core prompts in many encodings at

Assuming those packages don't meet your needs, this script doesn't do what
you intended.
Because you specified *wav, the ls -R is not recursing through the
directories, it's only listing the wav files in the specified directory.
Without the *wav, ls would recurse, but it wouldn't display the path.
The find command is a better tool for this.
Compare:
$ ls -R /var/lib/asterisk/sounds/*wav | wc -l
241
and
$ find /var/lib/asterisk/sounds/ -name '*.wav' | wc -l
1596
And then, a few suggestions* on better practices.
) Use $( and ) instead of back-ticks. They can be nested and they
survive emailing, printers (the human kind), telephones, and strange fonts
better.
) Use shell functions instead of processes. You create 2 processes for
every file just to substitute the file type.
) Use upper case for variables** so they stand out.
) Don't use single character variable names -- we don't code in FORTRAN
any more do we? Also, they're obtuse and a bitch to search for in an
editor.
) Use comments before a block of code instead of line by line.
# Recurse through the input path, [ab]using Asterisk*** to

INPUT_PATH=/var/lib/asterisk/sounds/
for INPUT in $(find ${INPUT_PATH} -name '*.wav')
do
OUTPUT=${INPUT%.wav}.g729
asterisk -r -x file convert ${INPUT} ${OUTPUT}
done
# (end of snippet)
I'm sure some shell weenie could code it all up in a single arcane line of
cruft, but the goal should be clarity and maintainability.
*) I recognize some of these suggestions reflect my religious beliefs.
If you all would get over it and just convert we can all just get
along.

for variables in shell scripts, but I do. Whatever case you prefer, be
consistent.

them had a funky header and it exposed a hither-to unknown bug?

Hi Steve,
Thank you for the extensive response, I'm using some UK prompts on my system so
would like to convert them to g729.
The new script and tips on scripting will be helpful.
Thanks
Kenny

[asterisk-users] Voiceprompts i.e. voicemail and conferencing in multiple codecs
Hi, I am running asterisk 1.6.1.6 with a howler screamer card. I have g729 and alaw trunks from a pbx /sip providers. The howler screamer will only transcode from g729 to alaw / ulaw but my voice prompts are in SLIN and throws errors when i try and access these applications. Is it simply a case of converting the prompts into other codecs and asterisk will pick these up?
