[asterisk-users] Some queries on g729 license.

[Darryl Dunkin]

"per call" means per terminating channel where encoding/decoding is
required. Termination could be to translate to another codec (with
another peer) or to Asterisk itself to handle menus, voicemail,
conference calls.

In the conference call setup, each caller uses a license.

	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.
