'support' - yes, 'licenses' - no. Asterisk supports passthrough, recording and playback of quite a few codecs for which there are no transcoding modules available at all (G.723.1, H.263/4, etc). G.729 falls into this category if there is no transcoding module loaded, or if there are no licenses available. The only time that Asterisk will not offer G.729 in an outbound negotiation is if the incoming channel is not in G.729 (so thus would require transcoding) and there is no transcoding path available. The same is true for other codecs that don't have transcoding available... but by definition, this is not 'passthrough'. Also, to clarify an earlier point, Digium makes all the standard Asterisk prompt sets available in G.729 format, so the built-in applications can be used on G.729 channels without requiring transcoding. -- Kevin P.
