Someone please clarify if
1- codecs - the NSLU2 can actually pass through G723/G729 if asterisk does not need to transcode. The concept is not clear to me. (VOSP natively uses G723 and ATA natively uses G723, what exactly does asterisk do in this situation?
2- modules - what exactly is it with embedded devices that can't support the "full" modules? is it storage space, CPU, ram?
