The way I understanding it - a license is required if the media has to 
be processed by the pbx core. Somebody please correct me if I'm wrong. 
To record the call, the pbx core will transcode the incoming stream to 
the its native format (SLINEAR?) and then write the stream out in your 
recording format (xlaw or GSM). In short, you'll need a G.729 license.
