AFAIK, you need one license for each channel that is transcoding from 
one given codec to g729 (or the other way around).

So if at any given time on an asterisk box you would have a maximum of 3 
simultaneous calls that are g729 at one end and ulaw at the other, you 
would need a license key for 3 transcoding channels.

Anyone, please correct me if I am wrong on this.
