All of which hassle and expense can be avoided by buying a license for
Digium's codec, which is tested to work well with Asterisk (and might
come with some support). And is pretty cheap per simul "call".
I wonder whether that "per call" means "per codec instance", which
could be multiple licenses on a single conference call, where multiple
(even if not all) parties are getting de/encoded simultaneously. And
whether there are other tools for editing (/mixing/transforming) g729
data, in realtime (streams) or not (files), and whether they require a
license. Ideally sox or equivalent would work on g729, maybe with a
codec plugin.
