asterisk users - Dec 2011 - File Convert

Hi users,

I have Asterisk 1.6.2.20 in Ubuntu 10.04. I am trying to convert a gsm file
to G729 using file convert, but I am facing error as follows,

file convert /tmp/welcome.gsm /tmp/welcome.g729
Failed to convert /tmp/welcome.gsm to /tmp/welcome.g729!
Command 'file convert /tmp/welcome.gsm /tmp/welcome.g729' failed.
[Dec 20 17:24:18] WARNING[2221]: translate.c:256 ast_translator_build_path:
No translator path from g723 to alaw
[Dec 20 17:24:18] WARNING[2221]: file.c:184 ast_writestream: Unable to
translate to format g729, source format gsm

Even though I have the module format_g729.so. Do I need to have licensed
G729 codec for this? or codec_g729.so?

Kindly let me know how to convert the file.

Regards

Yes. The g729 codec module requires a per-codec-instance license. In
your case you use a single codec for encoding the audio to G.729.

BTW: if this is a file you recorded, why convert it from gsm and not
from a higher-quality format? If this is from the stanard set of
prompts: any chance it is already available as g729?
