[asterisk-users] Some queries on g729 license.

	Did you find any operations trouble installing/using the Digium codec
with Asterisk? I'd be surprised if Digium's were hard to use with
Asterisk, considering they wrote and support both. Also can their codec
be used to pre-encode data to files from a Linux command/line? Or just
the Asterisk CLI mentioned earlier in this thread?
